Implementing Comparator raises ArrayIndexOutOfBounds

Question

I have a Java Webservice project using Spring and Primefaces. On Windows machines this runs well and it also ran well on Ubuntu 14. But the error occurs on Ubuntu 16 and also on Debian, although I am not sure if the issue is related to the operation system:

Whenever I have a class that implements Comparator, launching the application raises the following error:

It is always 1320 and I tried with different Java versions ...

please post also code causing the error, definition of comparator, how you make the call.... — Jordi Castilla, Aug 22 '16 at 12:13
See if you can reproduce this error in a [minimal, complete and verifiable example](http://stackoverflow.com/help/mcve). That would make it a lot easier for everyone to help you. With a little luck you may even stumble on a solution while trying to do that. — Ole V.V., Aug 22 '16 at 12:40

Stupid me, here is what happened:

It was Java and Spring version not working together as mentioned in the comment of the duplicate question. I wrote that I tried with different Java versions, just I forgot that from eclipse Tomcat will not care about the Java version as specified within JAVA_HOME.
