Supported Bukkit Versions
Changelog is on Github: https://github.com/TechFortress/GriefPrevention/releases
If you're using Java 7, please try to ask your host to update to Java 8 (It's strongly recommended to update to Java 8/ask your provider to update, since Java 7 is End-of-Life and vulnerable to security exploits, much like Windows XP is today.)
If you still insist on using Java 7, you'll have to grab a java 7-compiled version. There's one in the Github link, but please do note that such jar files are not approved by devbukkit staff.
