Please review the jpackage fix for bug [1] at [2].
Added fallback for creating DMG if original approach fails. In original
approach DMG will be created by providing app image to hdiutil. It was
noticed that helper sub-processes run by hdiutil to copy app image
sometimes crashed or failed during automated testing. Fallback approach
will create empty DMG and copy files manually. It was observed that in
this case hdiutil does not run sub-process that caused tests to fail, so
hopefully this workaround will fix issue. Both cases produces same
working DMG. Tests which failed due to this issue was removed from
ProblemList.
