Stefan Buzoianu commented on ARTEMIS-2780:
------------------------------------------
I apologize for the delay but I wanted to do tests not only on 2.12 but also on
2.14. I made a build compiled with OpenJDK on the Windows environment.
For a few weeks I had the impression that this issue was resolved once this bug
was resolved - https://issues.apache.org/jira/browse/ARTEMIS-2596. I suspected
that our problem of deleting libraries was related to the cleanup procedure.
After at least four weeks in which this bug - deleting the jars from the lib
folder - did not reproduce in 2.1, it appeared when a VM we were testing
shutdown due to a windows update.

If on 2.12 this issue when it appears leads to the deletion of all jars in
libs, in this case, on 2.14, the jars in the lib folder have been partially
deleted.
We added some logs on our version of 2.14 and noticed that the jars that were
previously loaded in CLASSPATH are deleted:
[https://github.com/apache/activemq-artemis/blob/8fe1bb1c833e65a706423d332aa2abd5ae38d87b/artemis-commons/src/main/java/org/apache/activemq/artemis/utils/SpawnedVMSupport.java#L204]
My observation is that the jars are partially deleted because the child process
that is created to do web tmp folder cleanup cannot successfully initialize due
to the fact that the JVM is shutting down.
In this case I have two questions:
1. What are the implications for keeping the cleanup on start and eliminating
it on stop? I did a test by adding a file and a folder in tmp folder. When the
Artemis service is started, everything that exists in the tmp folder is deleted
because _cleanupTmp():_
[https://github.com/apache/activemq-artemis/blob/91fc0c979f3357ac854c71b2560e6a45307e00b0/artemis-web/src/main/java/org/apache/activemq/artemis/component/WebServerComponent.java#L262]
2. Why do we have a stop cleanup as long as we have a startup? this stop
cleanup involves, in certain situations, deleting the jars attached to the
CLASSPATH from lib.
