Subject [collections] Re: [GUMP@brutus]: jakarta-commons/commons-collections failed
Date Thu, 03 Jun 2004 13:34:36 GMT
I looked into this wondering if somehow Gump had something 'stale' lying
around that caused it, but I see it is writing to an in-memory buffer &
reading from same, so no (at least not there). Could there be some stray
class "lying around" that could be out sync? I find that hard to imagine,
but will look if it is likely.

Also, since this is writing a class (behind a List interface) to bytes and
then reading (hopefully) same class back, I'm somewhat at a loss to see how
the problem can even occur. Any pointers?
