Hi! We have a crash inside the VM call during logs initialisation. Can async-profiler cause it?

java_error_in_idea_31844.log

We use a patched version of the async-profiler built from master d29cb86 (I can share dylib in DM)

The assertion error means an unhandled JNI exception has occurred in AttachListener thread before execution of a diagnostic command. The only scenario I can imagine is when env->NewStringUTF throws OutOfMemoryError. This is an unlikely event, but the crash report indeed indicates a low heap memory condition with 85 OutOfMemoryErrors happened. I committed the fix for such a case.
