Domenico Francesco Bruscino commented on ARTEMIS-2780:
------------------------------------------------------
By default, Jetty will create this directory inside the directory named by the
java.io.tmpdir system property, according to [jetty temporary directories
documentation|https://www.eclipse.org/jetty/documentation/current/ref-temporary-directories.html].
If your java.io.tmpdir system property is pointing to the lib path or a parent
path of the lib path, it would explain your issue.
The [ARTEMIS-2596 Move tmp web dir for a safe clean
up|https://github.com/apache/activemq-artemis/commit/819f1834f5342bd4d425d4c2ff83f3b0bbaef373]
commit sets the artemis web tmp folder so now the cleanup should only delete
files included in the artemis web tmp folder and not files at java.io.tmpdir.
The temporary web cleanup on stop deletes the files related to the loaded web
contexts, wherever they are.
The temporary web cleanup on start is a workaround procedure that tries to
delete temporary web files created by a previous execution terminated
abnormally. This procedure deletes all files included in the web tmp folder, so
also files not related to the web contexts. It can not delete temporary web
files in other folders than the web tmp folder.

> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Web Console
> Affects Versions: 2.11.0
> Environment: Artemis is configured to always use a personally built
> OPEN JRE java (not using the default one)
> * Artemis 2.11.0.
> * Windows 10
> * OpenJDK 1.8.0_66 (OPEN_JRE - C: \ work \ open-jre \)
> * Oracle JDK 1.9.0_191 (Environment variable JAVA_HOME - C: \ Program Files

> If you kill the server without invoking a normal shutdown, the contents of
> the lib folder (ArtemisRootDir/lib) are removed. This makes Artemis Brokers
> unable to start.
> My suspicion is that there is a certain incompatibility between my local
> Windows resources and the way ActiveMQ Artemis is configured. Can you check
> the attached files please?
