> Hi masters, from the code and log, we can see that OOM will terminateJVM
> directly, but Metaspace OutOfMemoryError will graceful shutdown. The code
> comment mentions: {{_it does not usually require more class loading to fail
> again with the Metaspace OutOfMemoryError_.}}.
> But we encountered: after Metaspace OutOfMemoryError,
> {{_java.lang.NoClassDefFoundError: Could not initialize class
> org.apache.flink.runtime.taskexecutor.TaskManagerRunner$Result_.}}, makes Tm
> unable to exit, keeps trying again, keeps NoClassDefFoundError, keeps class
> loading failure, until kill tm by manually.
> I want to add a catch Throwable in the onFatalError method, and directly
> terminateJVM() in the catch. Is there any problem with this strategy?
