If it passed I'll try to narrow the guilty changes.
The test passed on r522000 for 3000 iteration.
AFAIS in this interval was the sole drlvm commit: [r522033] H3413, refactor, cleanup of exception safepoint callback build.
Thanks. The result is: - the test is hang on the r522033 (iteration 143) - the test is passed already for 670 iteration on r522032. Could somebody from our thread guru evaluate it? thanks, Vladimir
