Please use the "admin" component within the glassfish JIRA project for a
bug on this issue.
Note that the top-level config-specific directory is synchronized, i.e.,
domains/domain1/config/c1-config/. So if you you put your JAR files in
there, then they will be synchrononized. Since the config needs to be
modified to reference the JAR files, it could just reference it from the
config specific directory rather than the lib directory under that.
