Hello all,
after load test of our application (that uses Jetty client for some functionality) we noticed that CPU is still being consumed 100%. Thread dump shows us 6 threads with the following stacktrace that eat all cpu:
"thread_name-166" prio=10 tid=0x00007f42546e1000 nid=0x4f84 runnable [0x00007f42963e2000]

Locked ownable synchronizers:

How can we debug it? What can be the cause? Any help is highly apreciated.
Jetty 9.0.7, Oracle Java 1.7.0_45 x64.
Regards,
Mikhail.
