> JVM can exit prematurely following framework teardown
> -----------------------------------------------------
>
> Key: MESOS-3264
> URL: https://issues.apache.org/jira/browse/MESOS-3264
> Project: Mesos
> Issue Type: Bug
> Components: java api
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Greg Mann
> Assignee: haosdent
> Priority: Minor
> Labels: java, tech-debt
>
> In Java frameworks, it is possible for the JVM to begin exiting the program -
> via {{System.exit()}}, for example - while teardown of native objects such as
> the SchedulerDriver and associated Executors is still in progress.
> {{SchedulerDriver::stop()}} will return after it has sent messages to other
> actors to begin their teardown, meanwhile the JVM is free to terminate the
> program and thus begin executing native object destructors while those
> objects are still in use, potentially leading to a segfault.
> This has manifested itself in flaky tests from the ExamplesTest suite (see
> MESOS-830 and MESOS-1013), as mutexes from glog are destroyed while the
> framework is still shutting down and attempting to log.
> Ideally, a mechanism would exist to block the Java code until a confirmation
> that framework teardown is complete has been received.
