Java 10 has now hit Debian as default, so I've started looking into fixing this. Basically, javac can now be told to generate the headers at the same time it generates the class files, by adding "-h subversion/bindings/javahl/include" to the existing javac calls. However, this only works with Java 8 or newer. Is it acceptable to bump our minimum Java version for building (and runtime?) to 8? I know we could still build for older Java versions while using newer toolchain, but even that has been emitting deprecation notices: /usr/lib/jvm/default-java/bin/javac -target 1.6 -source 1.6 … warning: [options] bootstrap class path not set in conjunction with -source 1.6 warning: [options] source value 1.6 is obsolete and will be removed in a future release warning: [options] target value 1.6 is obsolete and will be removed in a future release If we're fine with bumping up to Java 8, is that something we'd be willing to backport to 1.10 or would we need to add detection for what toolchain is being used?
