Shutdown thread error, classDefNotFound

[bitfinfo]

Hi,
We have tried our own shutdown hook and tried using HZ's built in
shutdown hook and consistently see this:

Anyone have any ideas on this and why it fails?

How are you calling the shutdown?

[bitsof...@gmail.com]

We tried calling it via Hazelcast's own "shutdown thread" and got this error. Then we tried our own Shutdown thread that just calls Hazelcast.shutdownAll() and same thing.

In addition to this kind of error, we have code that will detect a condition where hazelcast is not initialized. The code does a Hazelcast.shutdownAll(). The most bothersome thing about this is that sometimes (not all the time) when this is called, after the call we start getting tons of other ClassDefNotFoundExceptions, even for things like "javax/mail/Messaging" when other unrelated code executes. Almost like calling shutdownAll somehow affects our entire classloader, messing up the entire application. 

Any assistance appreciated.

[bitsof...@gmail.com]

Also can someone clarify the difference between hazelcastInstance.shutdown() or hazelcastInstance.getLifecycleService().shutdown and just Hazelcast.shutdownAll(). What is bothersome is that after a Hazelcast.shutdownAll() we cannot do a Hazelcast.init() against our conf file. Because the conf file (in our jar on the classpath) cannot be found after a shutdownAll(), (in addition to other ClassDefNotFoundExceptions for other classes)

[Mehmet Dogan]

hazelcastInstance.shutdown() is deprecated and calls hazelcastInstance.getLifecycleService().shutdown() inside.

hazelcastInstance.getLifecycleService().shutdown() shutdowns current HazelcastInstance.

 

Hazelcast.shutdownAll() shutdowns all HazelcastInstances created inside current JVM/Classloader.
