Exception connecting to KNX IP Router - Invalid argument

I am using the Calimero library to try and connect to my KNX system. The stack trace that keeps coming up is this:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'knxNetworkLink' defined in class path resource [io/symphony/knx/config/KnxConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [tuwien.auto.calimero.link.KNXNetworkLink]: Factory method 'knxNetworkLink' threw exception; nested exception is tuwien.auto.calimero.KNXException: connecting 127.0.1.1:41243 10.0.1.223:3671 (bound)

Something is an "invalid argument" but I don't understand what might be the problem. The code below is what I use: It's based on Springboot and I configure the connection via the application.yaml. Those values (only one in this case) get mapped into the KnxProperties object which I use further down to set up the KNXNetworkLinx bean.
application.yaml

Error in connecting to Google Cloud SQL com.google.cloud.sql.mysql.SocketFactory casting

com.google.cloud.sql.mysql.SocketFactory cannot be cast to com.mysql.jdbc.SocketFactory
The above error occurs when Java Web application deploys to google cloud and run it. This error occurs when retrieve values to database or insert to databse (login, register). Why that error occurs and how to fix it. Can anyone help me?

You don't need to import jdbc-socket-factory-core. It's a parent dependency, it's already pulled in from mysql-socket-factory-connector-j-8. Here is an example of the dependencies you need to have in your pom.xml.
You shouldn't need to cast the SocketFactory at all. Take a look at this example, which shows how to create a pool that uses the Socket Factory. Take special note of L60, which shows how to specify the SocketFactory.

How to set the hibernate.connection.password as an encrypted value in hibernate.cfg.xml and then decrypt it to be used in the config?

I am trying to create a encrypted value in the properties for hibernate.connection.password. At run time the encrypted value is picked up and decrypted. I then try to overwrite the properties in the HibernateUtil. But even after decryption the value doesn't seemed to be used because it fails to authenticate. How would I get this to work?
public class HibernateUtil {
private static final SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;
private static final String keyFile="/keys/.aoo1key";
static {
try {
Configuration cfg = new Configuration().configure("hibernate.cfg.xml");
String passwordToDecrypt=cfg.getProperty("hibernate.connection.password");
if(passwordToDecrypt.startsWith("ENC(")&&passwordToDecrypt.endsWith(")")) {
passwordToDecrypt = passwordToDecrypt.substring(4,passwordToDecrypt.length()-1);
PropertiesEncryption propertiesEncryption = new PropertiesEncryption(keyFile);
String decrypted = propertiesEncryption.decryptValue(passwordToDecrypt);
cfg.setProperty("hibernate.connection.password", decrypted);
}
StandardServiceRegistry standardRegistry = cfg.getStandardServiceRegistryBuilder().build();
Metadata metaData = new MetadataSources(standardRegistry).getMetadataBuilder().build();
sessionFactory = metaData.getSessionFactoryBuilder().build();
} catch (Throwable th) {
System.err.println("Enitial SessionFactory creation failed" + th);
throw new ExceptionInInitializerError(th);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}

I found that if I broke it down into steps I can get it to do what I want. I was doing the build at the same time I was instantiating the StandardServiceRegistry. That seems to have been the main problem with my code. Plus I found that I should set the decrypted password with standardServiceRegistryBuilder.applySetting and not with the Configuration object.
StandardServiceRegistry standardRegistry = cfg.getStandardServiceRegistryBuilder().build();
it works like this
public class HibernateUtil {
private static StandardServiceRegistry serviceRegistry;
private static SessionFactory sessionFactory =buildSessionFactory();
private static final String keyFile="/keys/.aoo1key";
// Hibernate 5:
private static SessionFactory buildSessionFactory() {
try {
Configuration cfg = new Configuration().configure("hibernate.cfg.xml");
// Create the ServiceRegistry from hibernate.cfg.xml
StandardServiceRegistryBuilder standardServiceRegistryBuilder = cfg.getStandardServiceRegistryBuilder();
//Get the encrypted value
String passwordToDecrypt=cfg.getProperty("hibernate.connection.password");
//Test if it is encrypted
if(passwordToDecrypt.startsWith("ENC(")&&passwordToDecrypt.endsWith(")")) {
//Stripping "ENC(" and ")"
passwordToDecrypt = passwordToDecrypt.substring(4,passwordToDecrypt.length()-1);
//TODO Key file is the key to use for decrytion, the name of my class PropertiesEncryption is kind of bad, what should I call it?
PropertiesEncryption propertiesEncryption = new PropertiesEncryption(keyFile);
String decrypted = propertiesEncryption.decryptValue(passwordToDecrypt);
//Overwrite the encrypted value
standardServiceRegistryBuilder.applySetting("hibernate.connection.password", decrypted);
}
//This will build even if the password wasn't never encrypted
serviceRegistry =standardServiceRegistryBuilder.build();
// Create a metadata sources using the specified service registry.
Metadata metadata = new MetadataSources(serviceRegistry).getMetadataBuilder().build();
return metadata.getSessionFactoryBuilder().build();
} catch (Throwable ex) {
if (serviceRegistry != null) {
StandardServiceRegistryBuilder.destroy(serviceRegistry);
}
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
public static void shutdown() {
// Close caches and connection pools
// getSessionFactory().close();
if (serviceRegistry != null) {
StandardServiceRegistryBuilder.destroy(serviceRegistry);
}
}
}

Play Framework Too many open files

We use the Play! Framework 2.3 with Java.
We have a major issue in production which stops our applications from running and sending out data to clients.
We get the dreaded "too many open files" error and have googled, but have no idea how to fix this! It happens every couple of days, here is the error:

Here is the actual API call that is trying to be executed:
public Result getTodaysFixturesByCompId(Long compId) throws JSONException, ParseException {
Logger.debug("Get Todays Fixtures by compId: " + compId);
List<Object[]> fixtures = fixturesService.getTodaysFixturesByCompId(compId);
// Loop through fixtures and create JSONObject response
ArrayList<JSONObject> fixList = new ArrayList<JSONObject>();
for (int i = 0; i < fixtures.size(); i++) {
JSONObject fixture = new JSONObject();
fixture.put("id", fixtures.get(i)[0]);
fixture.put("fixture_date", fixtures.get(i)[1]);
String fixtureDate = "" + fixtures.get(i)[1];
String fixtureTime = "" + fixtures.get(i)[2];
Logger.debug("fixtureDateTime: " + fixtureDate + " " + fixtureTime);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("Europe/London"));
Date date = sdf.parse(fixtureDate + " " + fixtureTime);
Logger.debug("Parsed date: " + date);
Time timeValue = new Time(date.getTime());
fixture.put("fixture_time", timeValue);
fixture.put("venue", fixtures.get(i)[3]);
fixture.put("country", fixtures.get(i)[4]);
fixture.put("team_id_1", fixtures.get(i)[5]);
fixture.put("team_id_2", fixtures.get(i)[6]);
fixture.put("competition_id", fixtures.get(i)[7]);
fixture.put("sheets_processed", fixtures.get(i)[8]);
fixture.put("team_name_1", fixtures.get(i)[9]);
fixture.put("team_name_2", fixtures.get(i)[10]);
fixList.add(fixture);
}
setAllowAccessOrigin();
return play.mvc.Controller.ok(fixList.toString());
}
And then my DataConfig class:
public class DataConfig {
#SuppressWarnings("serial")
#Bean
public EntityManagerFactory entityManagerFactory() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setShowSql(false);
vendorAdapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
entityManagerFactory.setPackagesToScan("models");
entityManagerFactory.setJpaVendorAdapter(vendorAdapter);
entityManagerFactory.setDataSource(dataSource());
entityManagerFactory.afterPropertiesSet();
return entityManagerFactory.getObject();
}
#Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager(entityManagerFactory());
return transactionManager;
}
#Bean
public DataSource dataSource() {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(Play.application().configuration().getString("db.default.driver"));

dataSource.setUsername(Play.application().configuration().getString("db.default.user"));
dataSource.setPassword(Play.application().configuration().getString("db.default.password"));
return dataSource;
}
}
The error seems to be on this line in my controller:
List<Object[]> fixtures = fixturesService.getTodaysFixturesByCompId(compId);
The fixturesService method:
public List<Object[]> getTodaysFixturesByCompId(Long compId) {
String jpql = "select *,(SELECT name FROM teams WHERE id=team_id_1) AS teamname1,(SELECT name FROM teams WHERE id=team_id_2) AS teamname2 from fixtures WHERE (DATE(fixture_date)=DATE(NOW()) AND (competition_id='" + compId + "')) ORDER BY fixture_date,fixture_time";
javax.persistence.Query query = em.createNativeQuery(jpql);
List<Object[]> results = query.getResultList();
return results;
}
Please help?

You leak DB connections. It's not in the code that you describe, try to look where you open connection to the DB and where you close it.

The current error is because you did not configure the hibernate.dialect properly, you can set it as below in your hibernate.cfg.xml file:
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
Also, ensure that the other properties are set with right property names:
hibernate.connection.driver_class = org.postgresql.Driver
hibernate.connection.url = yoururl
hibernate.connection.username = youruserid
hibernate.connection.password = yourpwd
hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
