I am using the Eclipse 3.2M5a version on Windows XP Professional. And ran across a small problem when I mis-typed the generic parameters for a nested static class. 

When creating a nested class, for instance:
/*
 */
public class Test<T,S> {
	
	public static class Randy<T,S> extends Test<T.S>{
		
	}

}

the editor fails to detect the period (".") between the T and S generic "parameters" in "extends Test<T.S>". Instead, a ClassCastException is thrown and prepended to the top of the file in question.

The stack (and shown as an error in the editor on the first line of the file) is:
