RFR 9: 8066750 broke jdk9 builds; backup the changeset

[Roger Riggs]

Please review the backout of the change for 8806750 which broke some builds
that have not yet removed a dependency.

Webrev:
   http://cr.openjdk.java.net/~rriggs/webrev-backout-8155182/

After the dependencies are cleared, I'll send a new review for the 
original removal.

Sorry for the hassle,
Roger
