Hi all,
I have written some code in Websphere 4.0 in AIX using:
jaxp 1_2_01, dom (level 2), sax (2.0), xercesImp (2.0.1 ), xalan 2.2.0.
I just try to use them to do some simple xml document building. Most of the time is run normally. However, some time it will throw the following exception:
[03.04.20 14:32:12:812 CST] 6902870a SystemOut U java.lang.StackOverflowError

It seems that the stack overflow problem is due to the getproperties method is automically called repeatedly until all the stack are used up.
Any idea?
Thanks first.
