[news.eclipse.technology.equinox] Matching feature versions

[Stephan Herrmann <stephan@xxxxxxxxxxxxxxx>]

Hi,

I was wondering, how the matching of feature versions happens.
Consider these features:
3.5RC3
  org.eclipse.jdt_3.5.0.v20090527-2000-7r88FEeFJePyvYe69JGnUag1
3.5RC4
  org.eclipse.jdt_3.5.0.v20090527-2000-7r88FEeFJePyvYeA27DiZdc1

It strongly looks like both are the same feature, only the last so-many
characters of this long identifier differ.

This is relevant in the context of deploying patch features, because a
patch must(?) specify the exact version of the feature being patched.

Is there a way to tell equinox / p2, that a given patch feature can indeed
be applied on top of either of the above (identical) features?

I seem to remember that those long identifiers were _intended_ to 
bring more stability to dependencies, whereas in this case they seem
to _introduce_ unnecessary incompatibilities.
Am I missing something?

thanks,
Stephan
