Go from JDT UI.

The test failure is transient and tracked in eclipse-jdt/eclipse.jdt.ui#79 (comment).

Tentatively JDT would like to merge this PR for RC1: eclipse-jdt/eclipse.jdt.core#4856.

The PR was merged. I can trigger SDK build now or wait for the nightly. What is preferred?

Since it's not too late at the day I assume there is a chance that some people check the new build.
Therefore I suggest to start a new build now.

OK, I will check eclipse-jdt/eclipse.jdt.debug#866 now (tests only), after that I will trigger SDK build.
