Uninstalling features doesn't remove plug-ins [message #121081]

Hi, I am testing the installation and uninstallation of a Feature from
Local Site with Eclipse R3.5 M3 and I have observed that when I
unsintall the Feature, it is removed from /fetaures directory but the
Plug-ins remains in /plugins directory. Is this the normal behavior?

Thanks in advance,

Chemi.

Same behavior in Eclipse R3.4.1. Any comment? I am searching the web
with no luck.

Thanks in advance,

Chemi.

Hi Chemi,

This is expected. The plugins are cleaned out by a garbage collection
process that is "off by one". By this I mean that your unreferenced plugins
will get removed after the next provisioning operation. We do this partly to
avoid a problem deleting files while the framework is still holding a
reference to the bundle open. After re-starting try installing something
else and you should see the bundles get cleaned up.

I see, thank you for the explanation.
BTW, what about clean them just after a restart? Why should we wait
until we install something else?

Thanks again,

Chemi.

Well, still some orphaned plugins exist in my plugins folder - left after plugins that are no longer installed on my eclipse. Maybe p2 is not trying to get rid of all unknown (not listed in features at least) .jars in plugins folder, but just tries to purge old versions when they are updated?
