Andrea Del Bene reassigned WICKET-6522:
---------------------------------------
Assignee: (was: Andrea Del Bene)
> ThreadLocal leak in PageStoreManager
> ------------------------------------
>
> Key: WICKET-6522
> URL: https://issues.apache.org/jira/browse/WICKET-6522
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 7.9.0
> Environment: Wildfly 10 on CentOS 7 Linux.
> Reporter: Klaasjan Brand
> Priority: Major
>
> One of our heavy-used Wicket production applications has developed
> 'interesting' behaviour since upgrading to 7.9.0: after a while the system
> becomes slower and seems to need more CPU time to handle the same amount of
> requests. Threaddumps exposed that a lot of CPU time was consumed by
> java.lang.ThreadLocal$ThreadLocalMap.getEntryAfterMiss, pointing to a
> ThreadLocal leak.
> After making a heapdump (20g) of one of our servers we found lots of
> ThreadLocalMap$Entry objects referenced by
> org.apache.wicket.page.PageStoreManager$SessionEntry$1 containing the value
> Boolean.FALSE.
> Seems that boolean is new behaviour introduced by the fix for WICKET-6465 and
> is causing complications on servers like Wildfly we use which don't recycle
> threads.
