When a jar is modified, the entryMap of the JarEntryHandler is not being refreshed if its content has changed. For example, a jar META-INF directory to which files have been added/removed is not being refreshed. Need to create a testcase for this.

This issue was marked as fixed for beta12 as JBVFS-7, but these test failures in beta19 look to be the same issue:
