> I systematically reproduce this behaviour on the linux boxes I tested with.
> The test gets stuck acquiring permits from a semaphore, normally used for throttling:
> "main" prio=10 tid=0x08058c00 nid=0x588d waiting on condition [0xf723c000]
> java.lang.Thread.State: WAITING (parking)
> at sun.misc.Unsafe.park(Native Method)
> - parking to wait for <0xb5619728> (a java.util.concurrent.Semaphore$NonfairSync)

> The issue might come from the synchronization mechanism used in the test itself.
