      Description

      I think I might have found a memory leak. I am running a load testing script that creates a bunch of nodes in a hierarchy of about 7 deep and then stores some binary properties of random sizes from 1024 to 16384 bytes into the nt:resource leaf nodes. It next runs a bunch of queries to find some random collection of nodes, modifies some properties and moves some of the node hierarchy around.

      After about 10 iterations with JBoss AS 7.2.0.Alpha1 configures with 1536K max heap the appserver heap hits 100% and the server stops in a continual garbage collection loop.

      Before I delve deeper I thought I would post this bug and attach some of the heap analysis I've done. THere seem to be a lot of char[] allocated in workspace cache. See the attached html from jprofiler.
