Do you mean like section 6.2 of Brian's document?
The VM does not "support" inner classes. Rather, inner classes are a
language construct implemented by compiler "magic". Inner classes are
translated by javac into ordinary (static) classes, with additional
fields representing captured state and enclosing instances. Brian's
document describes the translation of lambdas to primitives supported
by the VM.
