Subject [jira] [Commented] (AXIS-2862) Circular reference in Deserialization and XMLReader
Date Mon, 10 Oct 2011 11:45:29 GMT

    [ https://issues.apache.org/jira/browse/AXIS-2862?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13124008#comment-13124008

Sagara Gunathunga  commented on AXIS-2862:
------------------------------------------

Axis2 and axis1 are two different projects. Axis2 is not the latest version of Axis1 instead
Axis2 is a complete redesign of Axis1 architecture, each of these project has separate code
base, web site , Jira projects and separate communities as well. You have filled your axis2
related issue  on Axis2 Jira, hence you can't expect any help from here. Please use the link
provided in my previous comment to reach the correct Jira project for Axis1.

> 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.
