It happens when Java runs out of heap space. That may commonly happen when you:

- keep references to objects and never allow them to be garbage collections; this is as close to a memory leak as you can get in a Java program
- try to load a gigantic pile of data into memory, for example one or multiple huge images

How to resolve depends completely on the code that is causing it.

That exception is also used for other things. What comes after the ":" in that excecption message?

It could be heap space, it could be permgen space, it could be too many open file descriptors, it could be too many native threads, and, I believe another couple of things. IOW, the exception is CALLED "OutOfMemory" but what it REALLY is, is "OutOfSystemResource".

Ha, just call it "OutOfSomething" :)

I think it can also commonly happen when the swap is full on *nix environments.
