In my RCP application I extended the CommandContributionItem class but I
can't do this because in RAP it is declared as final and my code will no
longer compile.

Jon,

the RAP workbench code is based on 3.4. It seems that the "final"
directive has gone in the meanwhile.
However, the JavaDoc (3.4) reads "This class may be instantiated; it is
not intended to be subclassed.". If this is still true, you should
reconsider your approach in any way.

There is an enhancement request that covers to upgrade to a newer version:
309661: Update workbench code to Galileo (3.5) or Helios (3.6)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=309661

I guess it was final in 3.4, which is still the base version for the
workbench in RAP.

The Javadoc of this class says: "This class may be instantiated; it is
not intended to be subclassed."
