[jira] Created: (DIREVE-54) Comparator serialization issue causing a NPE

Comparator serialization issue causing a NPE
--------------------------------------------

         Key: DIREVE-54
         URL: http://issues.apache.org/jira/browse/DIREVE-54
     Project: Directory Eve
        Type: Bug
  Components: jdbm database  
    Reporter: Alex Karasulu
 Assigned to: Alex Karasulu 
    Priority: Blocker


On a restart using an existing database, JDBM tries to resusitate serialized comparators for indices.  Some transient properties are not there when deserialized and cause the NPE.  We need to have a clear strategy for how we intend to deal with this Comparator issue.

-------------------------------------

Here's a test case that makes bug occur:

http://svn.apache.org/viewcvs.cgi/incubator/directory/eve/trunk/backend/core/src/test/org/apache/eve/jndi/ComparatorNPEBugTest.java?rev=55750&view=auto

When this test passes we know that the bug is gone.

---------------------------------

    Resolution: Fixed

Committed revision 55762.

Switch from using a ThreadLocal as the basis for recovering underlying non-serializable comparators to using the global comparator registry.  Did on mass replacement of things.  You can take a look at the changes here:
