Lua is the programming language under the Codea app on the iPad, and has been used as "the language" to write games publishable on that platform.

I have Java on my Raspberry Pi, and it runs fine. Obviously I won't be running a large exposed database on it (due to storage capacity limits) or doing realtime aerodynamic simulation (due to CPU speed and memory capacity limits), but those are driven by the provisioning characteristics of my device and not driven by Java the language.

What Java doesn't do is target game consoles at all. Technically it's
possible, but it's not a practical reality for end developers at the
moment. Java/JVM->iOS is limited, although lots of games use RoboVM for
this. And Android uses Java, but the API is completely separate from other
platforms, so there is no write once type code sharing.
 
Most high-level languages are extremely cross platform. Lua, for example,
is extremely cross platform and is often used on top of a C-based game
engine.
 
Most of .NET's cross platform success is through the Unity game engine,
which is mostly written in C, but uses Mono/C# for scripting like other
games use Lua or UnrealScript. They also have MonoGame and tools for making
Android/iOS apps in C# using largely platform native APIs which prohibits
any type of write once code sharing.
 
Many languages like Haskell, usually just compile down to C, so I don't see
why those would be less cross platform friendly.

Apologies, I was a definitely too absolute in my claim. I was more just
going on admittedly anecdotal evidence that most truly cross platform
applications that aren't a) ugly, or b) dog slow are not written in Java
and related languages. I'm definitely open to counters.
 
But, once you get that list made, compare it to the number of applications
that are heavily used in many platforms and the language they used. From
the Kernel, which is on near everything, to browsers. Mozilla is at least
making a stab with a new language that will compete with C/C++. It isn't
clear this will win, though.

Lua doesn't try to be "the language" that you write your application in,
though. Or does it nowdays? Last I saw, it was picked specifically
because it was easy to embed in a C program.

I want to agree with you, but I would prefer evidence. :)
 
 
Also, and I apologize if this is basically goal post shifting, but when I
refer to cross platform, I don't necessarily mean just linux/mac/windows.
I mean something that can run on the raspberry pi, or aduino, or *any*
phone/tablet/whatever. Obviously, not just any C program can be made to
fit this bill. But, to my knowledge, no Java program can. (Of course,
maybe Angry Birds is all it takes to prove me wrong. Or Scumm games, in
general. :) )

If I'm not wrong Lua is also used by Adobe Lightroom, for the UI interface.

LUA is the default scripting language for most video games these days (including World of Warcraft) because it's trivial to embed, crazy fast and quite a reasonable language in the "C family" category.
