BugID: 4045331

I was using pce to edit a file which I'd just checked out via JWS when java dumped core.

The core file is
/home/evan/cores/core-java.041597

(it was /set/hotjava/hotjava1/kern/JWS/src/sun/jws/build/core.041597)

I don't know how to reproduce the problem. However,
I thought someone might investigate to see if there is enough information to
shoot this bug.
