[jira] [Created] (SLING-2471) Free classloaders as soon as possible
Carsten Ziegeler created SLING-2471:
---------------------------------------
Summary: Free classloaders as soon as possible
Key: SLING-2471
URL: https://issues.apache.org/jira/browse/SLING-2471
Project: Sling
Issue Type: Bug
Components: Scripting
Affects Versions: Scripting JSP 2.0.20
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: Scripting JSP 2.0.22
Currently if a classloader is marked as invalid, it is still kept around as jsps are only reloaded the next time they're accessed. This can lead to many stale classloaders if there is at least one loaded jsp which is not touched. Over time this can lead to perm gen problems as the number of stale classloaders increases

[jira] [Resolved] (SLING-2471) Free classloaders as soon as
possible

Carsten Ziegeler resolved SLING-2471.
-------------------------------------
Resolution: Fixed
I've changed the way the jsp scripts are hold. If now a jsp is reloaded and the class loader gets invalided all loaded scripts are asynchronously invalided. This frees the
classloader immediately and there is just one class loader used at a time.
In addition the classloader gets invalidated as soon as the jsp is changed and not
when the jsp is used the next time.
Some more improvements like less locking etc.
