Request for guidance on using possible future sets of javac options

Hello Joe,

The simplest way of accomplishing this currently would be to add lines 
like this to make/CompileJavaModules.gmk:

java.base_ADD_JAVAC_FLAGS := -Xdoclint:all/protected 
java.desktop_ADD_JAVAC_FLAGS := -Xdoclint:all,-missing/protected 

This assuming those modules are already setup to using -Xlint:all 
-Werror in make/common/SetupJavacompilers.gmk, which should be true for 
at least those two.

Is the separator ';' actually a path separator or always semi colon? If 
so, please use $(PATH_SEP). Also, a line containing a potential semi 
colon must always be quoted before given to the shell.
