[jira] Resolved: (JS2-1007) Null Pointer Exception in Page Manager
File Cache
[ https://issues.apache.org/jira/browse/JS2-1007?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Randy Watler resolved JS2-1007.
-------------------------------
Resolution: Fixed
Added tests to protect cache refresh/update notifications from PSML documents added to cache without parent folder set. This particular issue is probably not related to the new TTL or TTI "infinite" cache settings. It appears to be caused by concurrent page cache loading... something probably more common with multiple requests pending/synchronized on portal startup. Cache eviction could also increase the probability of this bug appearing.
Commit SVN revision: 774468.

> I am seeing this error, usually on the first hit, just starting today May 12, 2009. We just recently proposed changes to the ehcache setting since TTL and TTI are 0:
> <cache name="pageFileCache"
> maxElementsInMemory="${org.apache.jetspeed.ehcache.pagemanager.maxfiles}"
> eternal="false"
> overflowToDisk="false"
> timeToIdleSeconds="0"
> timeToLiveSeconds="0"
> memoryStoreEvictionPolicy="LFU"/>
> Im going to investigate upping these values
