static/inner classes

I recently came across the following compile error:

"inner classes cannot have static declarations"

AKA

class X

{

private class Y

{

private static int x;

}

}

There's quick and easy ways around this for me but I was wondering why from a technical standpoint this is disallowed in Java. Also, if you could point me to the language specification on this topic, that would also be helpful.

Thanks
