>using maven toolchain feature Are toolchains really needed, especially, 1.6 and 1.7? I believe Java "target=1.4" + Java 1.8 would be good enough. If there are javadoc "warnings or errors", we could just suppress it. At the end of the day, making the build 100 times harder by requesting Java 1.6 looks like an overkill.
I think there's no way to install Java 1.6 on modern macOS. Vladimir
