      Description

      jdk1.5 is working except for when I try to compare two dumps (jdk1.4 is not
      working at all but that's been reported).

      I've tried many permutations of jvm arguments including:
      -agentlib:hprof=file=dump.hprof,format=b
      and
      -agentlib:hprof=file=dump.hprof,format=b,doe=n,verbose=y,lineno=n

      >c:\jdk1.5\bin\java -jar hat.jar -baseline dump.hprof#1 dump.hprof#2
      Started HTTP server on port 7000
      Reading from dump.hprof#2...
      Dump file created Wed Dec 22 19:01:36 EST 2004
      java.io.IOException: Class 0x50000106 not found.

      The hprof file from a tomcat 4.1 session is too large to include so I'm hoping
      it can be reproduced easily. In the past, I have found leaks by taking two
      snapshots after test runs that end with invalidating the web session and
      looking for new objects.
