[jira] [Resolved] (AXIS-2863) Circular Reference in Deserialization
and XMLReader
[ https://issues.apache.org/jira/browse/AXIS-2863?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Veithen resolved AXIS-2863.
-----------------------------------
Resolution: Fixed
Fix Version/s: 1.4.1
Assignee: Andreas Veithen
Marking this issue as resolved. Nethanel has validated that the issue no longer occurs in his environment. In addition, with my changes it is now impossible to get the circular reference pattern shown in the description of this issue. If there are still issues with the Oracle SAX parser, then a new issue should be opened with additional information.

> I got out of memory error and when i analysed heap dump, i was getting infinite active references of deserialization and xmlreader.When expand Deserialization context,XMLReader reference is there and when expand XMLReader,Deserialization reference is there.It seems to be circular reference.The sample output of heap dump is given below.
