exporting dynamic-imported packages [message #83326]

Hi,
is it legal to Export-Package a package imported via Dynamic-ImportPackage?

When I try to do so, Eclipse complains that the exported package does
not exist in the plugin.

Strangely, if I Provide-Package the package, Eclipse does not complain
and everything works.

This difference in behaviour between Provide and Export package is due
to some semantic difference or is just a bug?

Thanks,
Sandro

The OSGi specification does not allow you to export a package which you
got from Import-Package (or DynamicImport-Package). Provide-Package is
not part of the OSGi specification and is not recommended in Eclipse.
It is only there to support bundles from Eclipse 3.0 that may have been
using it.

I'm surprised that Provide-Package actually allows you to re-export the
package you import. I would consider that a bug.
