Java, yes. We're talking about OpenJDK here, though. I know at least two
cases where OpenJDK has been put and sold on different embedded devices.
So, this is possible as soon as you *comply* with the *license*.
The corner case is hotspot, but if I remember correctly Cacao managed to
get the TCK running a mixture of Classpath and OpenJDK:
So there is at least at least an historical precedent.

I don't comment on this here, but I believe that, unfair as it is, if
Google used OpenJDK they would have avoided this. We have no proof of
this though, so it doesn't matter.

Well, this is a bit exaggerating, they are not super legal entities...

Nobody in the world ever violated the GPL so that no legal action was
ever required? Wow, so probably the GPL alone is indeed enough :)

It could be legitimate fear, which I partially share, but the way you
put it is really just FUD, really.
