Alexander Ashitkin commented on MJAR-192:
-----------------------------------------
@Kristian, will do.
@Michael the issue happens 1-2 times a day (~60 builds daily). Single threaded
build is ok. Unfortunately i cannot provide my project and reproducing case for
concurrency issue is complex. The best i can do is to try better debug logging
with patched maven.
thank you
