Hi Tom,
Thanks for the reply.. makes sense
I was just a bit confused by the statement -/* *'if an exported
package/ /of the bundle it references has been updated or removed'/ by
refreshPackages() - along with some differences I have noticed between
felix and equinox.
Feel free to bring the differences to our attention, we love to debate
these issues. :-)

The RequiredBundle#getRequiringBundles() is only intended to return
the bundles wired through Require-Bundle constraints. A RequiredBundle
object is removal pending as soon as the bundle content it represents
has been updated or uninstalled. The same rule for removal pending
applies to ExportedPackage objects. As soon as the bundle content
which exports the package has been updated or uninstalled then the
ExportedPackage becomes stale. This is related to the class loader
which loads the bundle content. If this class loader becomes marked
for removal because of an update or uninstall then all exported
packages available for load from that bundle class loader must become
stale as well as the RequiredBundle object.
Hope that helps.
Tom

[osgi-dev] RequiredBundle clarification - PackageAdmin spec
------------------------------------------------------------------------
Hi,
Apologies if this is clearly stated somewhere but I couldn't find an
explicit statement in the spec..
I just want to clarify something in relation to the
RequiredBundle#getRequiringBundles() method. Should this method return
all bundles that
are currently wired to the underlying bundle as a result of both
Require-Bundle and explicit Import-Package statements?
>From the spec:
"The information about a required bundle provided by this object may
change. A RequiredBundle object becomes stale if an exported package of
the bundle it references has been updated or removed as a result of
calling
PackageAdmin.refreshPackages()). If this object becomes stale, its
getSymbolicName()
and getVersion() methods continue to return their original values,
isRemovalPending() returns true, and getBundle() and
getRequiringBundles() return null."
To me, this implies that wiring as a result of explicit Import-Package
statements should also be considered.
If not, then should the RequiredBundle object only become stale when
the bundle it represents no longer exports any packages..
As long as it continues to export 1+ packages then any bundle
previously wired as a result of Require-Bundle would remain a valid
requiring bundle.
Thanks,
Alan _______________________________________________
