0005460: JSP compiler issue
(rep by Nikolay Fedorov)
We have experiences a problem on one of hour servers today. The resin sever was not responding. The number of request-processing threads was going up over time.
Attached is the the snapshot of thread stacks taken when the server was in this state.
I am not an expert in resin, but this particular thread looks suspicious:

"resin-port-6153-702 - 212.159.150.12" daemon prio=10 tid=0x00007f24b9d35000 nid=0x2988 in Object.wait() [0x00007f15ade2d000]
   java.lang.Thread.State: WAITING (on object monitor)
    at java.lang.Object.wait(Native Method)
    - waiting on <0x000000067752e940> (a java.util.concurrent.atomic.AtomicBoolean)
    at com.caucho.java.AbstractJavaCompiler.waitForComplete(AbstractJavaCompiler.java:149)
    - locked <0x000000067752e940> (a java.util.concurrent.atomic.AtomicBoolean)

See email Jun 14 for full stack trace.
