The second thread dump shows that the fileinstaller BundleActivator.stop
method is blocked

This seems like the file installer is blocking Bundle.stop. It would seem
that BundleActivator.stop should interrupt those watcher threads to allow
an orderly shutdown.
There may be a second order issue of why file installer is getting swept
up on the refresh. But the first order problem is why wont file installer
stop when requested.

Sorry I forgot to mention I'm cross posting to felix list also.
Anyhow, here is a stacktrace which shows the locking (search for
fileinstall).

Is there a bug/issue with the details? I don't know any details here. What
is the "concurrency issue with package refresh"?

Will there ever be a solution to the fileinstall on equinox issue?
It seems that fileinstall has not worked on equinox for some time due to
the concurrency issue with package refresh.
I believe 3.1.10 is the last version that works on equinox.
