Do the upstream projects have maintainers and are there bugs submitted to the issue trackers of the upstream projects?

Yes we do forward the fixes when the upstream projects are still alive, but many are no longer actively maintained unfortunately. And for Linux distributions rebuilding everything from sources, changes like stricter Javadoc rules, javac source/target modifications, tools removal and API deprecations hit us hard.

Just curious as it seems that many of the issues are you wrestling with won't be solved by extending the support for --release 6 to yet another release. Instead it seems, at least based on a quick browse of the bug report logs, that many of the issues relate to things were deprecated and eventually removed (javah, extensions mechanism, the legacy doclet API, ....) and it makes me wonder if some of these "packages" are actively maintained or not.

Yes they are, but we lack the manpower to actively fix mere build warnings that might break in the future. Packages are usually updated when a new version is available, to address security issues or fix build failures caused by toolchain changes. But we don't update packages just for replacing javah until it actually breaks.
