I'm getting a bit tired of seeing these JDK wide changes with lots of files touched.
Delete all changes in desktop from this PR and re-submit them as a separate PR.

Also do not change J2DBench. We deliberately avoid using new API so that we can take it and
run it on very old JDK versions to help track regressions.
