In volanotest run, there is "/usr/j2se/jre/lib/rt.jar: error reading zip file" error  in
server log.
It's a regression in mustang b45. Mustang b44 is fine.

The error happens on solaris sparc/x86, with -d64 and -server flags.
It takes about 5 mintues for the problems to happens on solaris sparc with flags -d64
-XX:+UseConcMarkSweepGC.

How to reproduce the problem:
0. log on to a solaris sparc machine ( let me ###@###.### know if you need access
to a bigapps machine )
1. export JAVA_HOME=<your java home>
2. execute the script /net/jtgb4u4c.sfbay/export/sail8/bigapps/tests/runvtest.ksh -d64 -XX:+UseConcMarkSweepGC
3. check the log file "vtestserver.out" under /bt/VolanoTest***.
   grep "error reading"
   Within 10 minutes, the error showed up in the log file.
4. Sometimes, when there was "error reading zip file" error in "vtestserver.out", there was "java.lang.NoClassDefFoundError: sun/net/ConnectionResetException" error in logs/error*** file.

I dropped b44's "libzip.so" into b45, and the problem went away.
b45's libzip.so does not work in b44.
