Kepler

I use the following command to run a workflow:
java -classpath build-area/lib/ant.jar:kepler.jar org.kepler.build.runner.Kepler -server -repository=chico1Repository -runwf -nogui /tmp/kar/8061.4.1.kar

under kepler directory.

The first time, it succeeded. However, when the second time it failed:
[null] Cached KAR contents
[null] Processing entry, LSID=urn:lsid:gamma.msi.ucsb.edu/OpenAuth/:8016:19:1, type=org.kepler.moml.CompositeClassEntity

If I deleted the .kepler, it worked again.
