reassign 576361 icedtea6-plugin
retitle 576361 Please don't link the plugin against libxpcom, libxul, etc.
thanks

Actually, the whole problem is icedtea6-plugin linking against libxul
and libxpcom when it doesn't need to:

dpkg-shlibdeps: warning: dependency on libxul.so could be avoided if "debian/icedtea6-plugin/usr/lib/jvm/java-6-openjdk/jre/lib/i386/IcedTeaPlugin.so" were not uselessly linked against it (they use none of its symbols).
dpkg-shlibdeps: warning: dependency on libxpcom.so could be avoided if "debian/icedtea6-plugin/usr/lib/jvm/java-6-openjdk/jre/lib/i386/IcedTeaPlugin.so" were not uselessly linked against it (they use none of its symbols).

(likewise for a whole bunch of libraries).

This also means the fix for bug #574679 (Cced) is wrong.

Cheers,

Mike
