We're having issues with Lucee hanging threads:

<https://dev.lucee.org/t/lucee-threads-hanging-java-util-concurrent-locks-reentrantlock-fairsync/11635>

I think this might be caused by LDEV-4064, but not totally sure.

Any thoughts on what might be causing this?

`createObject("java", "java.util.TimeZone")`
well <https://www.callicoder.com/java-simpledateformat-thread-safety-issues/> isn't thread safe, lucee uses it internally but via a thread safe pool

<@U070SQMD1>, This particular code has been stable for years (primarily under ACF). The way the instance of TimeZone is being used, I don't think it should be a problem. I'll definitely look into that though.

also as <@U06V253M4> suggested try the latest version, the ticket you cited was fixed since the version u are using?

<@U070SQMD1>, I'm trying to recreate the issue first, so I can verify it fixes the problem.
