LPS-50988

Hey Peter,

I thought that Master was supposed to be run on Java 7, but this comment makes it seem like plugins should still be compilable against Java 6:

https://issues.liferay.com/browse/LPS-47816?focusedCommentId=526752&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-526752

If it should only be run on Java 7, let me know and I can have Sam close out the LPS. Thanks!
