Why can't we have a static member within an inner class?

Tried compiling some codes and the compiler threw me "inner classes cannot have static declarations"

From the Java Language Specification 3rd Ed:



An inner class is a nested class that is not explicitly or implicitly declared static. Inner classes may not declare static initializers (�8.7) or member interfaces. Inner classes may not declare static members, unless they are compile-time constant fields. Inner classes may inherit static members that are not compile-time constants even though they may not declare them. Nested classes that are not inner classes may declare static members...



No reason is given why.

My guess is that since inner classes have access to the enclosing class' private instance values there was some potential issues with initializing a static member. You could initialize a static value based on the value inside an instance of the outer class.

If that's the reason, it would make sense to allow inner classes to inherit static members because the inherited members wouldn't have access to data from the instance of the enclosing class. And the problem is avoided.

Thank you all for your explanation.
