Description
The test fails with HS22 b06 and JDK6u29 b01. The failure is reproducible on linux-i586 with '-client -Xcomp' VM options in about 30 iterations.
Comments
We don't see failures in CyclicBarrier/Basic.java.

Anything that fails only with -Xcomp is still quite likely to be a compiler problem. The problem we see now is not likely to be the same problem as was reported for JDK 6.

I don't think we are seeing this failure in jdk9/dev, it would be good to understand if the failure with 9 is new or not (seems like the original issue with 6uX might have been something else).

Failure on nightlies of 04 07 2014 is with -server -Xcomp -XX:-TieredCompilation so without C1. That makes it very unlikely to be a compiler problem (fails with both compilers, C1 & C2 have very little in common).
