We have an eclipse RCP product where we have a validation plugin that does validate artifacts. In windows, it is working fine but in Linux, I'm getting the below exception.

[INFO]      [java] [emc.build] java.util.ConcurrentModificationException

Am I missing something or it is expected behavior? I'm using eclipse 4.12. For the older version of eclipse, everything was working fine.

Thanks in Advance.

Your question is kind of context free. The EMF services project is not highly active so best you debug this yourself...
