An updated specification can be found here:


This addresses a few bugs that were discovered since the Proposed Final Draft.  To avoid confusion, it also aligns the section numbers for Method Reference Expressions (15.13) with the integrated JLS 8 section numbering.

This will be submitted for publishing via the JCP page.

Full change log, from the document:

> Method References: Renumbered the Method Reference Expressions section 15.13 (to make room, the JLS 7 15.13 will be merged with a previous section).
> Typing and Evaluation: Added changes to 6.6.2 to clarify accessibility of references to protected methods.
> Type Inference: Bug fix for subtyping constraints involving the null type. Added rule to invocation typing for lifting constraints on nested invocation arguments that are lambdas/method references into the enclosing inference context.
