Bump Jenkins version to 1.500 (or something), put branch 1.4xx into maintenance and switch to Java 7. Java 7 is already at update 7. My $.02.

Re: [VOTE] Bump Jenkins to Java 6
Switching to Java 7 would be a mistake in my view based on the number of users listed in the current usage summary. If current development switches to Java 7, the Java 5 and Java 6 users will be stranded by a development choice, rather than making their own choice of JDK. I don't see enough benefit for Jenkins developers or Jenkins users in the switch from Java6 to Java7, and I see a large potential to alienate a very large portion of the user community if development switched to a Java7 runtime dependency. I'm in favor of switching from Java5 as the runtime dependency to Java6 as the runtime dependency. I assume it is one less thing to trouble the developers so they don't have to continually check that they have not inadvertently introduced a Java6 runtime dependency.

We aren't talking about requiring Java7. So let's not confuse this request for feedback with a different issue.
