Is there an extension point for forcing a plug-in to unload last? [message #44664]

I am aware of the org.eclipse.ui.startup extension point that (attempts) to
load your plug-in first. I need the complement extension point for forcing
a plug-in to unload last. We are providing run-time logging support and
after our plug-in is unloaded, callers cannot actively log shut-down events.

Thanks,
Paul

That's an interesting question. Frankly I don't know the answer. However, I
believe that this would hardly be possible because the whole runtime exists
of some (however few) plugins itself and so _they_ should actually be
closing down last.

This doesn't make sense to me. I'm assuming that the users of your logging
plugin are other plugins that have included your logging plugin in the
<requires> section of thier plugin manifest. If this is so then the
platform would not allow your plugin to shut down before its users.

Eric and Ted,
Thanks for your answers. Unfortunately, our situation is slightly more
complicated than plug-in dependencies. Our plug-in registers an
ILogListener instance with the Eclipse platform logger. Users do not 'have'
to require our plug-in to leverage the core logging functionality of our
product. When our plug-in unloads, we are forced to de-register this
ILogListener instance with the Eclipse platform logger thereby losing
valuable shut-down events.

Thanks again for your comments.
