It appears that test_java_integration hangs sometimes, when launched by 'ant regrtest'.
This is likely related to http://bugs.jython.org/issue2536, however
jstack output (attached) is different in this case. It doesn't detect a deadlock, but still test_java_integration hangs indefinitely.

However there are some similarities to jstack output of http://bugs.jython.org/issue2536:

- sun.misc.Unsafe.park is involved
- java.util.concurrent.locks.ReentrantLock$NonfairSync is involved
- Jython-Netty-Client is involved

Meanwhile I also observed a rather similar behavior happening in test_pythoninterpreter_jy.
jstack output attached.
