How to solve java.lang.NoClassDefFoundError in ear maven project?

Environment:
Jboss 7.2
Java 11
I try to execute a method in Commons modul from Front modul. Front module does not have jasper report dependency and execute a method from Commons modul that it uses jasper report library.
It is a migration from Jboss5.2 and it worked properly, but with Jboss7.2 I have some issues.
When I try to execute ReportManager methods (common module) from Front module it throws a java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRException
Any idea why is that?

You declared the scope to be provided which means that the artifact is not packaged into the EAR.
If it is not provided in any other way, calling the JAR will fail.

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniTest in java.library.path Eclipse

I am trying a Maven Project with javacpp from Eclipse, and the project builds, but when I try to run it, it gives an exception and terminates itself. I am pretty new to Maven and managing pom.xml files, and I don't know what to do. The exception is:

Cannot resolve symbol 'TestUnit' in maven project

I'm trying to learn JUnit Testing currently. I want to test first custom 'TestUnit' class but IDE tells me that Cannot resolve symbol 'TestUnit'. What I should do to fix this error?
TestUnit class:
package test.lessons.purejava;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class TestUnit {
#Test
public void testAdd(){
String string = "Test unit works";
assertEquals("Test unit works", string);
}
#Test
public void concatTest(){
Concatenation concatenation = new Concatenation();
String result = concatenation.concat("Hello", " World");
assertEquals("Hello World", result);
}

Spring RestTemplate & AsyncRestTemplate with Netty4 hangs forever

And a test case to demonstrate different usages of AsyncRestTemplate:

package com.example;
import com.netflix.hystrix.HystrixCommand;
import com.netflix.hystrix.HystrixCommandProperties;
import feign.RequestLine;
import feign.hystrix.HystrixFeign;
import feign.hystrix.SetterFactory;
import org.junit.Test;
import org.springframework.http.ResponseEntity;
import org.springframework.http.client.Netty4ClientHttpRequestFactory;
import org.springframework.http.client.OkHttp3ClientHttpRequestFactory;
import org.springframework.util.concurrent.ListenableFuture;
import org.springframework.web.client.AsyncRestTemplate;
import org.springframework.web.client.RestTemplate;
public class SampleTests {
private static final String URL = "https://api.github.com/users/octocat";
private static final int DEFAULT_SLEEP_MILLIS = 20;
private static final int DEFAULT_TIMEOUT = 10000;
#Test(timeout = DEFAULT_TIMEOUT)
public void syncRestNetty() throws Exception {
RestTemplate restTemplate = new RestTemplate(new Netty4ClientHttpRequestFactory());
ResponseEntity<String> response = restTemplate.getForEntity(URL, String.class);
System.out.println("response = " + response);
}
#Test(timeout = DEFAULT_TIMEOUT)
public void asyncRestNetty() throws Exception {
AsyncRestTemplate restTemplate = new AsyncRestTemplate(new Netty4ClientHttpRequestFactory());
ListenableFuture<ResponseEntity<String>> listenableFuture = restTemplate.getForEntity(URL, String.class);
listenableFuture.addCallback(result -> System.out.println("result = " + result), Throwable::printStackTrace);
while (!listenableFuture.isDone()) {
Thread.sleep(DEFAULT_SLEEP_MILLIS);
}
System.out.println("the end");
}
#Test
public void asyncRestOkHttp() throws Exception {
AsyncRestTemplate restTemplate = new AsyncRestTemplate(new OkHttp3ClientHttpRequestFactory());
ListenableFuture<ResponseEntity<String>> listenableFuture = restTemplate.getForEntity(URL, String.class);
listenableFuture.addCallback(result -> System.out.println("result = " + result), Throwable::printStackTrace);
while (!listenableFuture.isDone()) {
Thread.sleep(DEFAULT_SLEEP_MILLIS);
}
System.out.println("the end");
}
#Test
public void asyncRestHystrixFeign() throws Exception {
GitHub gitHub = HystrixFeign.builder()
.setterFactory((target, method) -> new SetterFactory.Default().create(target, method).andCommandPropertiesDefaults(HystrixCommandProperties.defaultSetter().withExecutionTimeoutInMilliseconds(10000)))
.target(GitHub.class, "https://api.github.com");
HystrixCommand<String> command = gitHub.octocatAsync();
command.toObservable().subscribe(result -> System.out.println("result = " + result), Throwable::printStackTrace);
while (!command.isExecutionComplete()) {
Thread.sleep(DEFAULT_SLEEP_MILLIS);
}
System.out.println("command.getExecutionTimeInMilliseconds() = " + command.getExecutionTimeInMilliseconds());
System.out.println("the end");
}
interface GitHub {
#RequestLine("GET /users/octocat")
HystrixCommand<String> octocatAsync();
}
}
When trying to run the tests which use Netty they just hang forever. (To see this please remove the JUnit timeout constraint). But if I run the exact same code with other clients everything works as expected.
I have tried different versions of Spring Boot and Netty but did not succeed. And from the logs everything looks ok.
What am I missing here?
EDIT:
Opened a ticket https://jira.spring.io/browse/SPR-14744 as suggested on Spring Gitter
EDIT-2:
Answer from Brian Clozel helped me find the issue which is related to Netty not realizing the server sent an empty response (a particular case with Github API and plain http) so I am marking it as accepted.

Can you try to configure your request factory with a Netty Sslcontext?
Netty4ClientHttpRequestFactory nettyFactory = new Netty4ClientHttpRequestFactory();
nettyFactory.setSslContext(SslContextBuilder.forClient().build());
AsyncRestTemplate restTemplate = new AsyncRestTemplate(nettyFactory);
Without that context, the client is trying to send plaintext requests to the https endpoint; in that case, you're probably getting an HTTP 400 response.
In your example code, the throwable should be an instance of HttpClientErrorException, and you could get that information by logging the response status or its body with exception.getResponseBodyAsString().

dom4j.Node iterate maps of elements

dom4j.Node to process xml files, and I had a problem with Map-similar structures.
I have followed document structure:
<Party>
<Identifier>1113ddbed7b54890abfe2f8c9754d689</Identifier>
<Address>
</Address>
<Contact>
<ContactInfo>
<Key>IPS</Key>
<Value>null</Value>
<Key>keyTwo</Key>
<Value>1234</Value>
(...)
</ContactInfo>
</Contact>
</Party>
And my goal is to get value for keyTwo element. How to get those element with flexible, non hardcoded way?
My first idea was something like that:
//parent node is father element
Node parentDocument = parentNode.selectSingleNode("ContactInfo");
List<Node> nodesKeys = contactNode.selectNodes("Key");
List<Node> nodesValues = contactNode.selectNodes("Value");
for(int i=0; i<nodesKeys.size(); i++){
if(nodesKeys.get(i).selectSingleNode("Key").equals("keyTwo")){
return nodesValues.get(i);
}
}
But I'm not sure if it is good approach, especially if list of keys and values will be correctly ordered.

Here is a complete working example:

<ContactInfo>
<Key>IPS</Key>
<Value>null</Value>
<Key>keyTwo</Key>
<Value>1234</Value>
</ContactInfo>
</Contact>

I think dom4j+Xpath will resolve the problem , you just need to add jaxen dependency.
// ContactInfo Element having key = 'keyTwo'
Node node = document.selectSingleNode( "//Party/Contact/ContactInfo[Key = 'keyTwo']");
// retrieve data from the selected node
String value = node... ;
