In 1.3 (from Beta through RC2), the "rmic" tool accepts but ignores the following command-line options, as quoted from its usage message:

  -sourcepath <path> Specify where to find user source files
  -bootclasspath <path> Override location of bootstrap class files
  -extdirs <path> Override location of installed extensions

In 1.2.2, the "rmic" tool functionally supported all of the following command-line options:

  -classpath <path> Specify where to find input class files
  -sourcepath <path> Specify where to find user source files
  -bootclasspath <path> Override location of bootstrap class files
  -extdirs <path> Override location of installed extensions

But now in 1.3, *only* the "-classpath <path>" option is actually processed; the others are parsed but otherwise completely ignored.
