java.util.jar.Attributes read WARNING: Duplicate name in Manifest

While opening JOSM I saw this:

WARNING: Duplicate name in Manifest: ru_Plugin-Description.
Ensure that the manifest does not have duplicate entries, and
that blank lines separate individual sections in both your
manifest and in the META-INF/MANIFEST.MF entry in the jar file.

Couldn't we have a message saying which plugin has problems/warnings?
As it is now it seems that it's not possible to know exactly which one has this problem.

Hmm, you you please try to find the plugin responisble for this:

unzip -c plugin.jar META-INF/MANIFEST.MF

Shows you the manifest of you files (Or try whatever zip tool you want).

Maybe also step-by-setp disabling the plugins should tell you.

greping every META-INF/MANIFEST.MF I only found imagery_offset_db.jar with ru_Plugin-Description:

Manifest-Version: 1.0

The strange thing is that even after disabling and removing this file, I still see one message:

WARNING: Duplicate name in Manifest: ru_Plugin-Description.
Ensure that the manifest does not have duplicate entries, and
that blank lines separate individual sections in both your
manifest and in the META-INF/MANIFEST.MF entry in the jar file.

But what I was initially thinking is if JOSM could print the affected/problematic plugin name (or filename).
I guess it won't be useful for the end user but somebody developing a plugin could see that there is some kind of problem with their code.

Should be fixed in [o32562] and [o32564]. Wrong Uppercase-entry and right lower-case entry caused that in the server-side manifest list.
