Hi , I see following stuck threads in openJPA code :
java.lang.Thread.State: RUNNABLE at java.util.TreeMap.getEntry(TreeMap.java:328) at java.util.TreeMap.get(TreeMap.java:255) at org.apache.openjpa.jdbc.schema.Schema.getTable(Schema.java:115) I think the root cause of the issue is because of unsynchronized TreeMap. There is a sun issue that explains the same about a hashMap and I think this is also because of the same issue explained in: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6423457 So, the fix is to synchronize the TreeMap but I do not have a replicable test case. I created a simple testcase that will create around 100000 treeMap entries and then around 50 threads trying to access this treeMap but unable to replicate the issue. Please suggest what you think should be done. Can I just submit the code fix ( synchronizing the treemap) and the test case ( even though unable to replicate ) ?
