@trebari where are we with my (off-line) suggestion to you that this fix be updated such that a System Property "-Djdk.allowTabbedWindows=true" be defined that lets someone over-ride the disabling so that folks can at least try out the effect of this on their apps whilst we figure out a supportable API ?
