Done @tillrohrmann. This is my first github pull request, so I didn't know
I needed to do that manually :-)
> Handle JVM Fatal Exceptions in Tasks
> ------------------------------------
>
> Key: FLINK-5718
> URL: https://issues.apache.org/jira/browse/FLINK-5718
> Project: Flink
> Issue Type: Improvement
> Components: Local Runtime
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Fix For: 1.3.0
>
>
> The TaskManager catches and handles all types of exceptions right now (all
> {{Throwables}}). The intention behind that is:
> - Many {{Error}} subclasses are recoverable for the TaskManagers, such as
> failure to load/link user code
> - We want to give eager notifications to the JobManager in case something
> in a task goes wrong.
> However, there are some exceptions which should probably simply terminate the
> JVM, if caught in the task thread, because they may leave the JVM in a
> dysfunctional limbo state:
> - {{OutOfMemoryError}}
> - {{InternalError}}
> - {{UnknownError}}
> - {{ZipError}}
> These are basically the subclasses of {{VirtualMachineError}}, except for
> {{StackOverflowError}}, which is recoverable and usually recovered already by
> the time the exception has been thrown and the stack unwound.
