Andreas Veithen commented on AXIS-2863:
---------------------------------------

There have been no changes in saaj and jaxrpc. It should be enough to replace the axis JAR.

> 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.
