---------------------------------------------------------------
[~pbacsko] you're correct, except in the old behavior we just failed
indefinitely and if value was null, assertion would fail and throw an error
that JMX service is unavailable. I may have introduced wrong behavior but test
only fails due to null value. We can move the assertion back after the catch
but it won't fix the failure. Again, I'm happy to work on this with some
direction. Also, behavior can be observed in the catch block when
jvm.memory.heap.committed is not available. Then it throws
InstanceNotFoundException
