Class#isMemberClass() returns false for DirectMethodHandle$Holder

A DESCRIPTION OF THE PROBLEM :
Calling Class#isMemberClass() on Class.forName("java.lang.invoke.DirectMethodHandle$Holder") returns false. The JLS leads me to think this should return true.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The following assertion fails:

assert Class.forName("java.lang.invoke.DirectMethodHandle$Holder").isMemberClass();


ACTUAL -
false

---------- BEGIN SOURCE ----------
assert Class.forName("java.lang.invoke.DirectMethodHandle$Holder").isMemberClass();
