FW: Problem using cobertura and tomcat 6.0

I'm trying to use cobertura to find code coverage by instrumenting my server side classes and using a Junit/HttpUnit client.  Things seem to go fine until I stop the tomcat process at the end of the test cycle.  Once that happens, my cobertura.ser file is corrupted and the following exceptions are logged in the tomcat catalina.out file.  Has anyone else seen something like this or have any suggestions for something to try?  It seems like too much of tomcat is already shut down for cobertura to update its results.

(Also posted to the cobertura list)

Thanks in advance,
Jeff
