Java lint service now do dry-compilation to get more accurate problem list. To save some CPU cycles, dry-compilation is avpided when only single line is modifed and deferred until line is inserted/deleted or cursor moves to another line. Also, wait a second before compilation process is triggered to give use a chance to finish his typing. Few more tweak here and there.
