While not entirely necessary, a conversion from Java 1.6 to 1.7 may be advisable.

Note:

• This would end JRE 1.6 support, ending support for a very small percent of users.
• Java 1.6 was marked EOL about two years ago, meaning that all java users have been encouraged to migrate already.
• Java 1.7 may run better in certain cases.
• Java 1.7 provides a few code niceties, such as the diamond operator and the try-with-resources statement.
• Other mods have already moved to Java 1.7

I am using 1.7

Really? The code is still compliant with Java 1.6, so I couldn't tell, sorry.

I'm trying to keep it compatible if possible

Ah.
