Hi Frank,
Probably best to confirm this on lambda-dev but I suspect that default method support introduced a bug in b63 that was fixed by b65.

Hi guys, I noticed there is a change in Java 8 between b63 and b65. The change can be illustrated by compiling following Issue class.
public class Issue { interface Handler { public void handle(); } interface Listener { public void listen(); } Handler handlerImpl = new Handler() { public void listen(Object... obj) { // do nothing } @Override public void handle() { new Listener() { @Override public void listen() { listen(null); } }; } }; } With OpenJDK 8 b65, compilation goes well whereas b63 failed, complaining that Issue.java:22: error: method listen in class cannot be applied to given types; listen(null); ^ required: no arguments found: reason: actual and formal argument lists differ in length 1 error Could anybody kindly take a look at it and point out what Oracle bug or feature has been built into b65 which is not available in b63? It would be very helpful. Best regards, Frank
