The javac launcher is equivalent to:

     1. detect -J options, set them to one side, removing -J

     2. exec java, with the processed -J options from step 1, with 
tools.jar on the classpath,
                     com.sun.tools.javac.Main  remaining-options

There is no extra arg decoding magic in the javac launcher, except to 
handle -J options.

Similar code is used for all the tool launchers; the only difference 
between them is the name of the entry point.

So, yes, javac accepts both -bootclasspath and -Xbootclaspath:, whether 
invoked from the launcher, or via javac.jar.
