Metrics web java modules should use Java 7 throughout

this includes code adaption to newer java features.

added component::metrics/website priority::high resolution::implemented severity::normal status::closed type::enhancement labels

Looks like we already made some progress in this direction in #21535 (moved). What remains to be done? Switch-on-String? What else?

Also try-with-resources and multiple exceptions. What else?

Please review my task-19730 commit. Raising priority a bit, because this is blocking other changes to the code base without risking a major merge mess. (Thanks!)

Trac:
Priority: Medium to High
Status: new to needs_review
Milestone: Metrics 1.0.0 to N/A

Looks fine. Good to move this.

Next time the code gets touched logging should be added and all the System.err.print* and e.printStackTrace should be replaced.

Awesome, thanks for the quick review! Pushed to master, deploying on meronense either later today or over the weekend. (Also agreeing about System.err.print*, plus we'll want to change all places where we're using different logging frameworks than slf4j. But that can happen independently of this ticket.) Closing. Thanks again!

Resolution: N/A to implemented

I just pushed another small commit to master that puts the constructors back which were actually still in use. Oops.
