I'd like to nominate David as a new committer for the RAP Incubator project.
With the implementation and port of the RAP-e4 compatibility layer he has shown a deep understanding of RAP.
Bug 518471 - E4/RAP Compatibility Layer Workbench
https://bugs.eclipse.org/bugs/show_bug.cgi?id=518471
Fortunately, David is willing to contribute his work back to the RAP Incubator and will help to maintain the port in the future.
Thanks and regards,
Markus
