For building master, anything from JDK 8 and later, theoretically, notwithstanding build tool bugs. The Guacamole source and build requires Java 8 as of GUACAMOLE-635, which will affect the in-progress 1.0.0 release and onward. This will be noted in the release notes when 1.0.0 goes out: https://issues.apache.org/jira/browse/GUACAMOLE-635 It's possible that some sort of workaround will need to be put in place if this affects the build even under JDK 8. This isn't happening in CI, but we also don't use Debian in our CI build. For 0.9.14 and older, the build requires Java 7 or later, however the source and resulting binaries are compatible with Java 6 or higher. - Mike
