---------------------------------------
Summary: Clean up threads or refresh threads when put back into
the pool
Key: SLING-4676
URL: https://issues.apache.org/jira/browse/SLING-4676
Project: Sling
Issue Type: Improvement
Components: Commons
Reporter: Carsten Ziegeler
Fix For: Commons Threads 3.2.2
A thread from the pool might use thread locals which are - for whatever reason
- not cleaned up, when the thread is put back into the pool.
This can lead to memory leaks.
We should protect against this.
Unfortunately there is no official API to clean up thread locals. There are
solutions out there using reflection.
Another option is to simply discard the thread object after some time of usage
and use a fresh one. This needs to include thread objects staying in the pool
for a long time
