Subject: [Patch] wrong fontification of Java code
Date: Mon, 1 Sep 2014 15:20:30 -0400

I have a potential solution for this bug, as it has impacted me as well.

Not sure what the best solution would be but I have included a patch that does solve the problem. From what I can tell there are no tests for java fortification but I have not seen any issues arising in my own java projects. The issue was that in java, a “:” can mark the end of a declaration in a foreach, not just a “;” or “,”.
