Linux doesn't keep stable ABI between kernel versions, so although it means binaries aren't compatible with old/new versions, it also means that a lot of cruft can be cleaned out, making it a more efficient, less bloated piece of software. Chances are, if you wanted you could take modern OpenJDK source and compile it against your old kernel. But there have been a lot of kernel fixes and improvements since F13, so it's probably worth the upgrade from a security standpoint anyway for anything that will be public-facing.
