Gregory Shimansky updated HARMONY-4158:
---------------------------------------
Summary: [drlvm][thread] VM sometimes throws unexpected InternalError on Thread.suspend() method invocation (was: [drlvm][thead] VM sometimes throws unexpected InternalError on Thread.suspend() method invocation)
> [drlvm][thread] VM sometimes throws unexpected InternalError on Thread.suspend() method invocation
