Thanks -- that was the problem.

I have installed the 1.6 JDK, and used "Java Preferences" to set it as
the default.  "java -version" and "javac -version" both report 1.6.
But, ant searches for various java implementations and finds first or
prefers the 1.5.  After setting JAVA_HOME I can run ant successfully on
splitter.  I have a patch to mkgmap/doc/README.java to explain this.
While it's perhaps overly tutorial, it's probably helpful to new people
who are only running java because of OSM.

Another mystery - after 'ant' I don't find dist/splitter.jar.  Do I need
to do something special to get a jar file?  The mkgmap ant build seems
to create this automatically.
