You mean as a way to circumvent the tool? Perhaps - though I would not want to do that either as this is a problem that could be seen in many call-chains that use JVM_ENTRY (and other cases) to get the "thread". In any case this has been reported as a false positive now.

What I may do is a RFE to add `current_thread_from_jni_environment` which will never return NULL and so avoid the issue altogether.

Cheers,
David
