This bug should have been fixed already (in graphics scrum). Can you please verify this? I don't have any Raspberry pi right now. Thanks.

Removing "required-for-embedded-ea2" label, as the comitted workaround is sufficient for ea2 release.

In the meantime I am going to revert the commit which causes the NPE, until the bugs mentioned above can be resolved (we'd like to get rid of the NPE in time for this weeks' promotion). Here is the commit, I will be reverting the changes done to Parent.java: changeset: 4447:ff1219a1e652 parent: 4445:074b23ebf5f1 user: Martin Sladecek <martin.sladecek@oracle.com> date: Mon Jul 29 13:33:12 2013 +0200 summary: RT-31919 ColorPicker, ArrayIndexOutOfBoundsException when saving custom color.

Per Martin Sladecek (via email): The stack trace indicates that this has the same cause as RT-31918 and should be also resolved by RT-29891. If the issue is critical I suggest reverting the fix below until RT-29891 is fixed. Assigning to Martin for verification when 31918 and 29891 are resolved.

The exception occurs in control code so I'm passing the bug there for initial evaluation.
