Message10676

Here's the jstack. The full output is rather large since the script creates 60ish threads but the deadlock is at the end so I've just included that.

Found one Java-level deadlock:
=============================
"Thread-80717":
  waiting to lock monitor 0x00007fd8e6041c28 (object 0x00000006c0fa89b0, a java.lang.Class),
  which is held by "MainThread"
"MainThread":
  waiting to lock monitor 0x00007fd8e2b39b28 (object 0x000000079c93fcd8, a org.python.modules._io.Closer),
  which is held by "Thread-80671"
"Thread-80671":
