Comment 2 jherkel 2015-07-01 09:50:28 UTC 
I also tried to remove --threads 1C and it seems that without this everything works correctly.
Comment 3 Tomas Stupka 2015-07-01 14:33:54 UTC 
tried with a bunch of maven projects but wasn't yet able to reproduce

any chance to provide or point to a project where this exception occurs with -T 1C?

thanks

Please try this test project. I was able to reproduce this bug also with Netbeans 8.0.2 (Fedora 21 64bit, jdk 8u45 64bit, maven 3.3.3)
