Since it is useful to return a non-null result in such cases, I've updated the spec to mention this case. The names of synthetic classes are not covered by the JLS; using a "$" in such names is customary, but not strictly required. The synthetic classes used to implement lambdas and method references as cited in the bug report include "$"'s.
