[FIXED JENKINS-15380]. Add some length checking before trying to substring names in ClassResult.

The plan of the record is that we start producing 1.6 class files and
see if people start complaining. If we hear from users, we'll re-visit
our decision, and if we don't, then we'll start using 1.6 features
everywhere in the code.

Add German translation for TextParameterDefinition.DisplayName

The slave launch thread is another background thread, and it should run
like a super-user

Fix German i18n for Maven deploy

simplify RestartListener.Default using getBusyExecutors()

"ausbringen" is not the correct word, use "veröffentlichen" instead.
This has some overlap with maven release, which is also translated as
"veröffentlichen", but it's obvious from the target name that follows.

German translation of pronouns (ref. https://github.com/jenkinsci/jenkins/commit/effcc2d7aa4f40a3f43185ab0bc22619d6ecea97)

(Could consider throwing IAE if it does not appear to be.
Cannot easily call getRootPath().absolutize() since that requires a connection.)

... as per the discussion in the dev list

This can track items as they go through the queue.

Setting a nonempty contextPath turned up a couple problems in the test harness; goTo must be given a relative path.

[JENKINS-18326] add maven site support for nested submodules
Thanks!

[JENKINS-16845] Properly report the IllegalStateException, rather than throwing an NPE producing the exception message.
java.lang.NullPointerException

See f8916a839c5a7bfe6d0de100a33cf23de33de6e4 for the corresponding change in the remoting.

Since the error messages only use ASCII

As Jesse pointed out, contextual information is often useful in authenticating the build, which means we need to take Queue.Item (initially AbstractBuild was the parameter, which provided the context, and I failed to accommodate that in transition to AbstractProject.)

To still allow Queue.Tasks to provide a meaningful value fallback to Queue.Task.getDefaultAuthentication() as opposed to hard code it to ACL.SYSTEM. This allow plugins like remote-terminal-access to supply a meaningful secure value without forcing a configuration change to the user.
