I just learned about a company today called Fiorano Software and I'm surprised they've flown under my Enterprise Integration radar for so long. Along with their overall platform, they provide an ESB with a P2P, asynchronous architecture based on JMS 2.0, so they are firmly in the Java enterprise world.
They just released a new version of their commercial platform – Fiorano 10 – and added support for SWIFT standards, which are pretty useful for financial messaging transactions. You can find more info about the platform release in their press release.
I was surprised I couldn't find anything about Fiorano in Crunchbase or other news sites, but it seems that they've faded from the spotlight a bit since the company's 1995 debut. However, they still are sitting pretty with customers like NASA, AT&T Labs, Vodafone, and L’Oréal.
