I think I have a problem with the java release flag, reported by a user here: https://github.com/ThreeTen/threeten-extra/issues/91
The particular case that is a problem are the new methods on java.lang.Math. Java 8 had these methods: floorDiv(long,long) floorDiv(int,int) Java 9 has these methods: floorDiv(long,long) floorDiv(int,int) floorDiv(long,int) (there are similar new overloads for other method names) Clearly, if you build on Java 9, code can link to the new(long,int) overload, but that code will get a NoSuchMethodError on Java 8. But, I am using Java 9 with the javac release flag set to be 8. If I understand the release flag correctly, the (long,int) overload should not be visible, and thus a different overload should be selected. So, is this a bug? Perhaps the tool that captures new method signatures doesn't handle overloads? (ThreeTen-Extra v1.3 was built using Maven on Java 9 using Maven's implementation of the release flag, so it could be Maven that is buggy, but I don't think so as it produces the correct classfile version number). thanks Stephen
