Hello all;
In the review for JDK-8029795 Paul Sandoz noted that HashMap.computeIfAbsent would generate a spurious access event for keys mapped to null when the function returned null. This patch corrects that behaviour.
http://cr.openjdk.java.net/~mduigou/JDK-8030016/0/webrev/
The actual regression test is LinkedHashMap/ComputeIfAbsentAccessOrder.java whereas the changes to Map/Defaults are improvements to the existing tests suggested by this bug (though they would not detect it).
Cheers,
Mike
