SonarQube 6.0 - org.sonar.java.se.ExplodedGraphWalker$MaximumStepsReachedException: reached limit of 16000 steps for method

I have created a custom rule for the sonarqube, Its working fine for a small java file file but when i am testing it under a large java file (more than 300+ line of code) then i am getting the below error.

java.lang.VerifyError when trying to mock javax.sql.DataSource class

Here is the block of code that is causing the error:
javax.sql.DataSource dataSourceMock = mock(javax.sql.DataSource.class);
when(dataSourceMock.getConnection()).thenReturn(mock(Connection.class));
dummyProcCall = Mockito.spy(new AbstractProcCall(dataSourceMock) {
#Override
protected String getProcName() {
return "Dummy Procedure";
}
});
Stacktrace is:

Steps I have taken to isolate the issue:
Try different JDK versions (JDK 1.7, 1.8)
Restart the machine and remove global JAVA_HOME
Try running the unit test without the IDE

What this error is all about? How could I fix this?
I've read this discussion, but I can't find an answer there.

NettyComponent just setup the timer when it is started. So you need to start the camel context first, in this way CamelContext can start the component by default.
CamelContext context = new DefaultCamelContext();
context.start();
context.createProducerTemplate().sendBody("netty:tcp://localhost:5150", "dummy");

ExceptionInInitializerError on variable initialization

I imported a project into eclipse and added the dependenciues (Just oracle drivers and junit4). But when I try to run the project I get a ExceptionInInitializerError. I can't initialize certain variables for some reason.
I know the project is okay so I think it is a problem with the JDK.
I have tried goggling it but I didn't get any solution.
Any help would be greatly appreciated.

Your DAO tries to get the connection to the DataSource in BaseDaoImpl's insert method on line 121.
com.inetwork.common.dao.BaseDaoImpl.insert(BaseDaoImpl.java:121)
You probably don't want to connect to a real database.
You will need to also somehow mock the Connection object and have the DataSource.getConnection() method return your mock.
