FULL PRODUCT VERSION :
Java HotSpot(TM) Client VM (1.6.0-rc-b62) 

A DESCRIPTION OF THE PROBLEM :
running an application i develop, i chose the "About" menu item, and the VM crashed. that code will have wanted to pull an image from the JAR file, which presumably explains the crash being in ZIP_GetEntry.

i haven't seen this before, and have been running Java 6 weeklies with this application on and off for weeks.

I've got something more useful; it's another similar crash in the same place (in the VM) from a different place (in my code). again, it's loading a class from a JAR file. i've been running this application with Java 6 builds for several weeks, and fairly often too, and these are the only two crashes i've had. they've been the same crash, and they're with the same build.
