Can anyone provide info on a java bug

Hi,

I am currently investigating a java error that is occuring
intermittantly. The error seen is

java.lang.NullP ointerException
at com.sun.jndi.ld ap.Connection.r un(Connection.j ava)
at java.lang.Threa d.run(Thread.ja va)

We areusing jdk 1.3.0_00 and know that this error is caused by known
java bug with Sun ref#4359598. I am having some trouble finding
information on the bug however and this is needed to make a decision
on how to move our environment forward.

Any information that can be provided on this would be great.

Thanks in advance
