Fixed issues with the custom flags that arose due to API changes in WG7 (you will have to use at least the Beta 1 version of WorldGuard for this and future versions to work)
Made it possible to run plugins without the javax module (which versions above 8 no longer include by default). This doesn't mean that every feature will definitely work when using Java 9+, it's just that a couple issues that were noticed wont happen anymore on them.
