The stuff is OSS, but I don't compile it myself, I just let the vendor or the 
community do the legwork. But I can ssh into the RPI and see that there is 
Linux installed and pretty much everything else running under java (openjdk8). 
The community-driven version is called Raspberrymatic:

IMHO, many people do not recognise that embedded platforms and such were the 
original target market for java when it was invented by Sun's engineers.

Sure, OpenJDK is the quasi-standard these days. GNU people quit on gcj long 
ago, but there is quite a bunch of different projects based on OpenJDK 
meanwhile:

Selecting a language heavily depends on the intended use and context. If it is 
just for yourself, there is far less to consider than in other circumstances.

Ah, well, in some places gcc really sucked, but they improved many things over 
the years. What I don't really like these days is the habit of doing major 
releases by the calendar, but many other projects have picked up that, too. 
Everything develops into the direction of more or less doing rolling releases 
for everything. I can live with that, but it makes maintenance for "appliances" 
that are supposed to "just work" based on this software a real hassle at times.
