Thank a lot for the rebuilds and the detailed analysis Chris! This gives a clear direction for our transition plan.

I've updated maven-compiler-plugin to the latest version, so we can now build projects with Java 9 code. But that didn't solve the language level issue. For the source/target tweak I modified plexus-compiler, it might be more general and fix more packages than the patch you used. > Of 1261 packages compiled, 57% failed.

This is caused by the removal of the 'jre' directory in Java 9 and the subsequent modification of the java.home property. This is easy to fix. > 18% still are trying to use old -source/-target: > https://paste.debian.net/974407/ > Perhaps some cases ant doesn't catch it, as it doesn't look > like a Debian build environment? It looks like my Ant fix doesn't work for packages defining the ant.build.javac.source and ant.build.javac.target properties (typically in debian/ant.properties). I'll look into this. > 11% (plus probably a lot of the above 23%) are failing doclint after > otherwise compiling successfully. doclint should be disabled, > but isn't: http://bugs.debian.org/866908 > > Hopefully everyone agrees we should fix this in the toolchain, as the > above bug. Yes, doclint must die :) > 7% are broken because invalid ASCII in the code is now an error; > it appears that it was only a warning on Java 8. This is now fixed for the packages built with javahelper and jh_build (#866845). > And, on a more positive note: > > 16% are broken due to probably intentional changes in Java 9, e.g. > * introduction of java.lang.Module > * modules changing accessiblity of things (~90 packages) > * _ becoming a keyword (~15 packages) > * apparent generics changes causing new casting problems(?) This is the interesting part, I'll dive into this once the obvious toolchain fixes are done. Emmanuel Bourg
