RFR: JDK-8189782: As com.sun.tools.javac.api.JavacTool misreports number of arguments consumed

[Jan Lahoda]

Hi,

JavaCompiler.isSupportedOption returns 1 for options like "-proc:none", 
which does not seem right. The proposed patch resolves that.

Bug: https://bugs.openjdk.java.net/browse/JDK-8189782
Webrev: http://cr.openjdk.java.net/~jlahoda/8189782/webrev.00/

How does it look?

Thanks,
