> Example of a failure: http://94.72.60.102/viewLog.html?buildId=565513
> {code}
> [18:07:47] :	 [Step 10/11] FATAL ERROR in native method: Invalid global JNI handle passed
to DeleteGlobalRef
> [18:07:47] :	 [Step 10/11] FATAL ERROR in native method: Bad global or local ref passed
to JNI
> {code}
> UnmanagedTarget class releases JNI handles in finalizer.
> Finalizers run at non-deterministic time. Due to some irrelevant changes there may be
failures sometimes. Need to ensure that we do not release the same handle twice, and that
we pass correct handles from unmanaged code.
