Inner classes must be addressed as package.OuterClass$InnerClass instead of package.OuterClass.InnerClass

My source code looks like this:

package test.byteman;

public class OuterClass {
	// ...
	
	public static class InnerClass {
		// ...
	}
}

When addressing InnerClass, I would have expected to use a CLASS statement like this:

CLASS test.byteman.OuterClass.InnerClass

But Byteman does not see a class matching this statement. When I change it to

CLASS test.byteman.OuterClass$InnerClass

Byteman sees the class and applies the rule. I would either expect the former statement to work (possibly in addition to the $ notation) or this behavior to be documented with the CLASS statement.

Example rule:

RULE trace call
CLASS test.byteman.OuterClass$InnerClass
METHOD myMethod
AT ENTRY
IF true
DO System.err.println("entering method")
ENDRULE
