- * Tests if we are running an acceptable Java and terminates JabRef when we are sure the version is not supported.
- * This test uses the requirements for the Java version as specified in gradle.build. It is possible to
- * define a minimum version including the built number and to indicate whether Java 9 can be used (which it currently
- * can't). It tries to compare this version number to the version of the currently running JVM. The check is
- * optimistic and will rather return true even if we could not exactly determine the version.
- *
- * Note: Users with a very old version like 1.6 will not profit from this since class versions are incompatible and
- * JabRef won't even start. Currently, JabRef won't start with Java 9 either, but the warning that it cannot be used
- * with this version is helpful anyway to prevent users to update from an old 1.8 directly to version 9. Additionally,
- * we soon might have a JabRef that does start with Java 9 but is not perfectly compatible. Therefore, we should leave
- * the Java 9 check alive.
