Summary

0006016: RegexpModule$RegexpCacheItem.get(RegexpModule.java:2471) hangs

Description

I am running some quercus scripts in parallel (with an Executor), and it intermittently hangs. Running a threaddump on the process shows a bunch of threads blocked:

"pool-1-thread-36" 0000059 prio=5 os_prio=0 tid=0x0000000022e8b000 nid=0x3424 waiting for monitor entry [0x000000001e92e000]
