Clean-room implementation of Double::toString(double) and Float::toString(float)

my code is now ready to be uploaded to the OpenJDK reps. Currently it 
resides on GitHub and is under the "GPLv2 + Classpath Exception" 
license, with myself as the copyright holder.

I asked Oracle about how the copyright notice should be adapted to meet 
the OCA requirements but, as of today, I got no answer.

Is there any official reference about the copyright notice on OpenJDK
