It really isn't that mysterious. It is just a couple of us guys and
girls having fun with hacking on and assembling some free software
stuff, mostly based around OpenJDK and for a large part consisting of
people who have also been involved with other free software java
projects for GNU/Linux like GNU Classpath, cacao, kaffe, gcj, etc.
There is nothing "shadowy" about it, just look at
In a way you can see it as an continuation of all the ideas which we
shared around GNU Classpath. Creating a large, enthusiastic bunch of
people, communities and companies working on all aspects of libre java,
working together in harmony.

We do. IcedTea comes with applet plugins, based on gcjwebplugin and
Deepak is now extending the new IcedTeaPlugin with
or ./configure --enable-liveconnect). I recently added javax.script
added VisualVM integration (./configure --enable-visualvm), although
that drags in a big piece of NetBeans (also under the GPL now), so we
are looking at how to package that easier/separately. I believe the only
thing not integrated yet is JavaDB, but I don't really know any programs
using that. If there actually are, we can certainly add that to the mix.
As extras IcedTea also comes with cacao integration as replacement for
hotspot on those platforms that hotspot hasn't been ported to
(./configure --with-cacao). And Zero as hotspot based interpreter
(./configure --enable-zero) and shark a jit backend for hotspot still in
development (./configure --enable-shark).

That has been and always will be the goal. Sun (or any company really)
cannot do it all alone (maybe partly crippled by some of those business
decisions you mention), and that is why we are here to help out wherever
we can and provide us all with a completely free Java implementation,
integrated well, and as free as you would expect from anything bundled
with a GNU/Linux distro.
