What issue did you run into without patching ToolProvider?  I have assumed
the build always launches javac/javadoc main class and not using
ToolProvider.

580 JAVAC_MAIN_CLASS = -m jdk.compiler.interim/com.sun.tools.javac.Main
581 JAVADOC_MAIN_CLASS = -m 
jdk.javadoc.interim/jdk.javadoc.internal.tool.Main Mandy
