This sounds strange, please open a bug
with steps to reproduce.

I've encountered the very same thing using 3.10.100.v20140909-1314
(built from source)

This happens even if the same bundle providing the optional
package is reinstalled.

Thus, if the bundle is there when first resolving the
"client" bundle, everything is great. The moment either bundle
is re-resolved, then the optional package does not wire.

Hey!

I have an issue with optionally imported packages and I have no idea what
is exactly going on or how to diagnose this in more detail.
We have a bundle that defines Import-Package, marked as optional.

org.apache.maven.project;resolution:=optional

There is a bundle (org.eclipse.m2e.maven.runtime) that exports this package
and everything is wired just fine.
Now I install a new version of m2e and therefore the exporting bundle is
updated to a new version.

But after the update, the optional package import is not wired again. I
would expect this to be wired to the new version of that org.eclipse.m2e.maven.runtime
bundle, but that doesn’t happen. There are no other bundles in the system
that export this package. A “diag <bundleID>” (with the bundle
ID of the importing bundle) doesn’t return anything.

Any idea what might be going on? All this is on Equinox 3.10.1.v20140909-1633
(Luna SR1, I think).
Or any idea how to investigate this in more detail?

(I already tried to restart Eclipse with -clean, but the result is the
same, the optional import isn’t wired and I don’t see a potentially package-use
conflict anywhere)

Thanks a lot for your help!
-Martin
