I've known for a while that RBS is using the NetBeans Platform but those I queried about it weren't allowed to comment because of internal policies re endorsing third party products. (By the way, that's the no. 1 reason why at least hundreds more NetBeans Platform applications continue to remain unknown.)
Anyway, today I put a couple things together which combine to provide 100% proof that RBS is using the NetBeans Platform, without RBS needing to provide any kind of permission to make this public. The proof consists of two pieces. The first is here, where someone named Conall Flood, clearly from RBS, asks a question about an application he's creating on the NetBeans Platform (and distributing via JWS), which looks as follows, which I know to be true since he included the screenshot in the e-mail:
The second piece of evidence is here, Conall Flood's LinkedIn profile, which is pretty clear in indicating he's an experienced developer at various banks. From July 2006 – April 2009, Conall worked at RBS, where he was "located on the trading floor working directly with spot and algo
traders in an Agile environment. Delivering quality software with
extremely quick turnaround timescales. Delivered auto hedging and
pricing of client flow solutions, an internal exchange, comms layers, a
generic modular gui solution for all High Frequency Trading aps."
Something developed at RBS as "a generic modular gui solution for all High Frequency Trading aps", combined with a NetBeans Platform screenshot that has "High Frequency Trading" in its title bar, is pretty clear evidence that RBS is explicitly invested in the NetBeans Platform. Welcome to the club, RBS.
