Issues accessing a single Kernel instance from multiple threads. #32

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Execute a single Kernel instance from many threads
2.
3.

What is the expected output? What do you see instead?
Expect to see each thread to execute correctly (although we can't expect data 
integrity)

Please use labels and text to provide additional information.
Instead we get an JVM crash. 

This is the latest branch for supporting Multi-Dim kernel access.  But I 
suspect the same issue will be in the main branch.

My guess is that we are inadvertantly sharing JNIEnv* data across threads.  I 
just checked in a potential fix (in the multi-dim branch) but can't really test 
until Monday.

Fix included with #r258 branch merge. We no longer rely on stored/share JNIEnvs.
