very strange nullpointer exception in soap call

[Yuan Ye]

Hi,

I have implemented a soap method using was6.0. Got strange nullpointer exception while the method is invoked from remote requestor. Here is the error stack trace.

The strange thing is on line 11 of ProcessRtm, it doesn't even try to create an instance of object RtmInfo, it calls the new method of a differnt object. Line 26 is the actual line that initialize the RtmInfo.

And this problem only appears on production system, I can't even duplicate it on test environment.

Please give me some hint if you have any insight to the problem.

Thanks.
