> In GlassFish, I detected a hang. PFA jstack output. The scenario happens like this:
> a) I updated a bundle using telnet console. This thread is holding the bundle lock.
> b) Upon receiving the UPDATED event, one of our extenders bundle enhances the bundle
and calls PackageAdmin.refreshPackages(bundle).
> c) PackageAdmin thread holds the global lock and tries to hold the bundle lock, which
is currently held by telnetconsole thread.
> d) telnetconsole thread is waiting indefinitely to obtain the bundle lock.
