The JDK-8003898 problem is a workaround for the bigger:
X11 toolkit is not supported for Mac OS and need to be removed.
The build system seems ready for this, in that configures "checking for X" fails gracefully in the absence of X11 bits. Windows does not explicitly skip those checks so I see no reason to do so on the Mac as well.
