Hi Benjamin,

Unfortunately we can't accept pull requests (contributions) unless you're on the Oracle Contributors List.

See here: http://www.oracle.com/technetwork/community/oca-486395.html

It's a very simple process and costs nothing, but also provides everyone, including yourself, with IP protections. Unless of course you work at Oracle, in which case I can accept the pull request immediately.

Regards
