As far as I understand, Java 9 will be released September 21.
Now we plan to release Log4j 2.9 before the end of July.
Given the problems that Java 9 causes, at least for Android, I suggest
that we de-scope the Java 9 specific stuff (StackLocator) from the 2.9
release.
It should be possible to do a 2.10 release with the Java 9 specific
stuff before September 21, right? And if not, that's not a disaster
since the 2.9 release will still work with Java 9 (just with non-optimal
performance for locationInfo), right?
I would say it's more important that log4j-api works on Android than we
get optimal performance for locationInfo on Java 9. Especially now when
Java 9 is not even officially released.
