I have not tested it, but it seems to me that
FindPackageHandleStandardArgs.cmake is the one handling the setting of
this variable IMHO.

$ cat Modules/readme.txt
...
XXX_EXECUTABLE          Where to find the XXX tool.
XXX_YYY_EXECUTABLE      Where to find the YYY tool that comes with XXX.
...

I decided to go for: Java_JAVA_EXECUTABLE / Java_JAVAC_EXECUTABLE/
Java_JAR_EXECUTABLE. It make it easier to write in a foreach loop. I
could leave them as such and add a Java_EXECUTABLE.

Comments ?
