Summary

0005940: Resin requires JDK 8 to compile

Description

It came as a surprise after a minor update from 4.0.42 to 4.0.44 that the newer version requires a class which is available in the JDK8 only.

That eventually broke a stable version in Gentoo Linux, see the following bug report for more details:
https://bugs.gentoo.org/show_bug.cgi?id=558442 [^]

It is not specified in the documentation (http://caucho.com/resin-4.0/admin/starting-resin-install.xtp) [^] either.

Is this class really unavoidable? I suggest to find a workaround and not to raise the requirement unnecessarily.

Notes
(0006650) kazssym 09-19-15 22:07	I worked around by introducing a version of TypeVariable compatible with Java 7. See <https://bitbucket.org/kazssym/quercus/commits/8f112f7ce220ed54cda21b75906702d6cf571cf1> [^]

(0006655) anton_kg 10-17-15 18:09	Apparently, it's other way around. Resin44 does support java7 but fails to compile with java8. Gentoo devs has introduced a patch (https://gitweb.gentoo.org/repo/gentoo.git/diff/www-servers/resin/files/4.0.44/VarType.java.patch?h=project/libressl&id=57db769be72ea2e2de2fc479202a4708a9c1e24f) [^] and it broke java7 support. They apply the patch optionally after the bug report.

(0006656) Joseq 10-19-15 19:50 edited on: 10-27-15 10:12	Anton is correct, and I don't know what I'm talking about. Ignore my original message below. No, that's incorrect. The patch introduced by Patrice Clement into the portage tree makes it so that Resin 4.0.44 will compile with JDK 7. I did not say "fixes" because the nicest thing I can say about that patch is that it's probably harmless. It might also cause null pointer exceptions under some circumstances. I wouldn't run it in a production environment.
