ZipException: zip END header not found in java-9

util.zip.ZipException: zip END header not found
exception when try to load javafx fxml view in java-9.
Details
My Application is a Javafx(uses fxml view) which is built and compiled using java-8(jdk-8 64-bit) and accessed as a WebStart with jre-9(64-bit).
Webpages(xhtml) are loaded and rendered in this javafx application.
Also note that
There are already two similar bugs reported (ie. JDK-8170276, JDK-8172872) and
these two bugs mentioned that the issue is not reproducible with latest java-9
but reproducible only with earlier java-9 ea build version.
But in my case, im using latest java-9(9.0.4 version) and
its always reproducible.
Problem
When i try to load fxml popup after login, get below exceptions.

Many Thanks.
Although this is not the full code, but this is the code for showing fxml popup which throws "java.util.zip.ZipException: zip END header not found" exceptions in java-9, but in java-8 works fine.

instance is null after renaming project

I'm working in IntelliJ and I attempted to rename my Project! After doing so, and renaming everything, which I believe I did correctly, I'm unable to actually start my application.

The error points to my Config class, however I'm not sure why:
public class Config {
private MochaMessages instance = MochaMessages.getInstance();
private FileConfiguration config = instance.getConfig();
public Config() {
}
public String get(String node) {
System.out.println("Fetching: " + node);
return config.getString(node);
}
public void set(String node, String value) {
config.set(node, value);
}
public boolean getBoolean(String node) {
System.out.println("Fetching: " + node);
return config.getBoolean(node);
}
}
Which is being called via my MochaMessages class:
Here's the related method:
private static MochaMessages instance;
private Config config = new Config();
public void onEnable() {
instance = this;
createConfig();
te = getTokenEnchant();
if (!config.getBoolean("database.enabled")) {
disablePlugin("Enable MySQL!");
} else if (config.get("mocha.currency").equalsIgnoreCase("TokenEnchant")) {
if (te == null) {
disablePlugin("Unable to access TokenEnchant. Disabling Plugin!");
}
} else {
Bukkit.getServer().getPluginManager().registerEvents(new MochaListener(), this);
new MochaModel().createTable();
new CommandHandler();
}
}
I believe it's because instance is returning null even though it shouldn't be. This worked perfectly before the rename!
What's going on?

Spring Integration | DSL

I am trying to send a file to Remote SFTP server. I have created a factory and an outboundFlow for the same.
UploaderSftpConnectionFactoryBuilder
#Configuration
public class UploaderSftpConnectionFactoryBuilder {
#Value("${report-uploader.sftp-factory.host}")
private String host = null;
#Value("${report-uploader.sftp-factory.port}")
private Integer port = null;
#Value("classpath:${report-uploader.sftp-factory.privateKey}")
private Resource privateKey = null;
#Value("${report-uploader.sftp-factory.privateKeyPassphrase}")
private String privateKeyPassphrase = null;
#Value("${report-uploader.sftp-factory.maxConnections}")
private String maxConnections = null;
#Value("${report-uploader.sftp-factory.user}")
private String user = null;
#Value("${report-uploader.sftp-factory.poolSize}")
private Integer poolSize = null;
#Value("${report-uploader.sftp-factory.sessionWaitTimeout}")
private Long sessionWaitTimeout = null;
//#Bean(name = "cachedSftpSessionFactory")
public DefaultSftpSessionFactory getSftpSessionFactory() {
DefaultSftpSessionFactory defaultSftpSessionFactory = new DefaultSftpSessionFactory();
Optional.ofNullable(this.getHost()).ifPresent(value -> defaultSftpSessionFactory.setHost(value));
Optional.ofNullable(this.getPort()).ifPresent(value -> defaultSftpSessionFactory.setPort(port));
Optional.ofNullable(this.getPrivateKey()).ifPresent(

Optional.ofNullable(this.getPrivateKeyPassphrase()).ifPresent(

Optional.ofNullable(this.getUser()).ifPresent(value -> defaultSftpSessionFactory.setUser(value));
return defaultSftpSessionFactory;
}
#Bean(name = "cachedSftpSessionFactory")
public CachingSessionFactory<LsEntry> getCachedSftpSessionFactory() {
CachingSessionFactory<LsEntry> cachedFtpSessionFactory = new CachingSessionFactory<LsEntry>(
getSftpSessionFactory());
cachedFtpSessionFactory.setPoolSize(poolSize);
cachedFtpSessionFactory.setSessionWaitTimeout(sessionWaitTimeout);
return cachedFtpSessionFactory;
}
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public Resource getPrivateKey() {
return privateKey;
}
public void setPrivateKey(Resource privateKey) {
this.privateKey = privateKey;
}
public String getPrivateKeyPassphrase() {
return privateKeyPassphrase;
}
public void setPrivateKeyPassphrase(String privateKeyPassphrase) {
this.privateKeyPassphrase = privateKeyPassphrase;
}
public String getMaxConnections() {
return maxConnections;
}
public void setMaxConnections(String maxConnections) {

}
public void setPort(Integer port) {
this.port = port;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
}
Now i want to test the outbound flow using an integration test. For that i have created below testContext:
TestContextConfiguration
#Configuration
public class TestContextConfiguration {
#Configuration
#Import({ FakeSftpServer.class, JmxAutoConfiguration.class, IntegrationAutoConfiguration.class,
UploaderSftpConnectionFactoryBuilder.class })
#IntegrationComponentScan
public static class ContextConfiguration {
#Value("${report-uploader.reportingServer.fileEncoding}")
private String fileEncoding;
#Autowired
private FakeSftpServer fakeSftpServer;
#Autowired
#Qualifier("cachedSftpSessionFactory")
//CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
DefaultSftpSessionFactory cachedSftpSessionFactory;
#Bean
public IntegrationFlow sftpOutboundFlow() {
return IntegrationFlows
.from("toSftpChannel")
.handle(Sftp.outboundAdapter(this.cachedSftpSessionFactory, FileExistsMode.REPLACE)
.charset(Charset.forName(fileEncoding)).remoteFileSeparator("\\")
.remoteDirectory(this.fakeSftpServer.getTargetSftpDirectory().getPath())
.fileNameExpression("payload.getName()").autoCreateDirectory(true)
.useTemporaryFileName(true).temporaryFileSuffix(".tranferring")
).get();
}
#Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
I have also created a fake sftp server as suggested # https://github.com/spring-projects/spring-integration-java-dsl/blob/master/src/test/java/org/springframework/integration/dsl/test/sftp/TestSftpServer.java
Below is my fake server:
FakeSftpServer
#Configuration("fakeSftpServer")
public class FakeSftpServer implements InitializingBean, DisposableBean {
private final SshServer server = SshServer.setUpDefaultServer();
private final int port = SocketUtils.findAvailableTcpPort();
private final TemporaryFolder sftpFolder;
private final TemporaryFolder localFolder;
private volatile File sftpRootFolder;
private volatile File sourceSftpDirectory;
private volatile File targetSftpDirectory;
private volatile File sourceLocalDirectory;
private volatile File targetLocalDirectory;
public FakeSftpServer() {
this.sftpFolder = new TemporaryFolder() {
#Override
public void create() throws IOException {
super.create();
sftpRootFolder = this.newFolder("sftpTest");
targetSftpDirectory = new File(sftpRootFolder, "sftpTarget");
targetSftpDirectory.mkdir();
}
};
this.localFolder = new TemporaryFolder() {
#Override
public void create() throws IOException {
super.create();
File rootFolder = this.newFolder("sftpTest");
sourceLocalDirectory = new File(rootFolder, "localSource");
sourceLocalDirectory.mkdirs();
File file = new File(sourceLocalDirectory, "localSource1.txt");
file.createNewFile();
file = new File(sourceLocalDirectory, "localSource2.txt");
file.createNewFile();
File subSourceLocalDirectory = new File(sourceLocalDirectory, "subLocalSource");
subSourceLocalDirectory.mkdir();
file = new File(subSourceLocalDirectory, "subLocalSource1.txt");
file.createNewFile();
}
};
}
#Override
public void afterPropertiesSet() throws Exception {
this.sftpFolder.create();
this.localFolder.create();
this.server.setPasswordAuthenticator((username, password, session) -> true);
this.server.setPort(this.port);
this.server.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(new File("src/test/resources/hostkey.ser")));
this.server.setSubsystemFactories(Arrays.<NamedFactory<Command>>asList(new SftpSubsystemFactory()));
this.server.setFileSystemFactory(new VirtualFileSystemFactory(sftpRootFolder.toPath()));
this.server.start();
}
#Override
public void destroy() throws Exception {
this.server.stop();
this.sftpFolder.delete();
this.localFolder.delete();
}
public File getSourceLocalDirectory() {
return this.sourceLocalDirectory;
}
public File getTargetLocalDirectory() {
return this.targetLocalDirectory;
}
public String getTargetLocalDirectoryName() {
return this.targetLocalDirectory.getAbsolutePath() + File.separator;
}
public File getTargetSftpDirectory() {
return this.targetSftpDirectory;
}
public void recursiveDelete(File file) {
File[] files = file.listFiles();
if (files != null) {
for (File each : files) {
recursiveDelete(each);
}
}
if (!(file.equals(this.targetSftpDirectory) || file.equals(this.targetLocalDirectory))) {
file.delete();
}
}
}
Finally below is my test class
TestConnectionFactory
#ContextConfiguration(classes = { TestContextConfiguration.class }, initializers = {ConfigFileApplicationContextInitializer.class})
#RunWith(SpringJUnit4ClassRunner.class)
#DirtiesContext
public class TestConnectionFactory {
#Autowired
#Qualifier("cachedSftpSessionFactory")
CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
//DefaultSftpSessionFactory cachedSftpSessionFactory;
#Autowired
FakeSftpServer fakeSftpServer;
#Autowired
#Qualifier("toSftpChannel")
private MessageChannel toSftpChannel;
#After
public void setupRemoteFileServers() {
this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getSourceLocalDirectory());
this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getTargetSftpDirectory());
}
#Test
public void testSftpOutboundFlow() {
boolean status = this.toSftpChannel.send(MessageBuilder.withPayload(new File(this.fakeSftpServer.getSourceLocalDirectory() + "\\" + "localSource1.txt")).build());
RemoteFileTemplate<ChannelSftp.LsEntry> template = new RemoteFileTemplate<>(this.cachedSftpSessionFactory);
ChannelSftp.LsEntry[] files = template.execute(session ->
session.list(this.fakeSftpServer.getTargetSftpDirectory() + "\\" + "localSource1.txt"));
assertEquals(1, files.length);
//assertEquals(3, files[0].getAttrs().getSize());
}
}
Now when i am running this test, I am getting the below exception:

You are connecting to the wrong port.
The test connection factory listens on a random port - you need to use the same port.

Jetty Websocket servlet InstantiationException problems

I'm having problems to make the websocket example of jetty work
public class App {
public static void main(String[] args) {
Server server = new Server(8080);
ServletHandler handler = new ServletHandler();
server.setHandler(handler);
handler.addServletWithMapping(MyEchoServlet.class, "/test/*");
try {
server.start();
server.join();
} catch (Exception e) {
e.printStackTrace();
}
}
public class MyEchoServlet extends WebSocketServlet {
#Override
public void configure(WebSocketServletFactory factory) {
//factory.getPolicy().setIdleTimeout(10000);
factory.register(MyEchoSocket.class);
}
}
#WebSocket(maxMessageSize = 64 * 1024)
public class MyEchoSocket {
Session session;
#OnWebSocketConnect
public void onConnect(Session session){
this.session = session;
System.out.println("init "+session.getUpgradeRequest().getRequestURI().getPath() );
}
#OnWebSocketMessage
public void onText(String msg) {
System.out.println("rec "+msg );
try {
session.getRemote().sendString(msg);
} catch (IOException e) {
e.printStackTrace();
}
}
#OnWebSocketClose
public void onClose(int statusCode, String reason) {
System.out.println("MyWebSocket.onClose()");
}
}
}
gives the following error as soon as I try to create a Websocket from javascript:
var ws = new WebSocket("ws://localhost:8080/test/");

Since you have that declared both your servlet and socket as inner classes, change the following 2 lines of your code ...
// From
public class MyEchoServlet extends WebSocketServlet {
// To
public static class MyEchoServlet extends WebSocketServlet {
// From
public class MyEchoSocket {
// To
public static class MyEchoSocket {
This is because Java cannot just instantiate a non-static inner class.
Try this from your main() method and you'll see ...
Servlet test = new MyEchoServlet();
