Yes. This (and some related cases) were not originally intended
supported usages, but someone pointed out last spring that the spec
did not rule them out. So it is now explicitly covered in revised
base sources, that have been running successfully for months
(including in Android builds). We usually let changes settle for
a while before merging into openJDK . This should be among the
next ones to merge in.
