RE: [equinox-dev] How to use Extension bundles in equinox
|
The spec is pretty clear on terminating the VM in these
situations however this can cause problems when embedding Equinox in another
process.
I can't really see a way around this for bootclasspath
extensions however for framework extensions I think we could just discard the
framework class loader and re-start the whole launching process without exiting
the VM. This might not be appropriate in all cases as there still would be
potential for there to be global state hanging around however I'm a bit curious.
Is this worth looking into in?

Yes the framework will relaunch,
but you must launch with the eclipse.exe. If a framework extension is
refreshed then the Framework will exit with an exit code indicating to
eclipse.exe that the framework should be relaunched in a new VM
instance.
Note that
updating/uninstalling framework extension bundles do not automatically cause
the framework to relaunch. The framework will only relaunch if
PackageAdmin.refreshPackages is called and it causes a framework extension to
be refreshed.

Thanks for the reply, Tom.
I have a question left.
Will
the framework shutdown and relaunch automatically when the
extension bundle
is refreshed, updated, uninstalled., and so on as
described in Section 3.15
?
