javac 8/9 inconsistency

[Maurizio Cimadamore]

Hi Anna,
I remember now - this is indeed:

https://bugs.openjdk.java.net/browse/JDK-8055963

That problem was ultimately caused by an ambiguity in the spec - which 
is why the fix was targeted for 9 and hasn't been backported. I would 
say it's normal for these kind of spec-related fixes to target the next 
release and not being backported.
