      Description

      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

      java.lang.NullPointerException
