This patch has been created very crudely by fixing compiler errors line by line leaving
//SB jy25
marks whereever there were changes. This is not a proper port to jython 2.5, but it compiles and works.
Would be nice if jython pro took the time to review and fix this permanently, since it is a useful enhancement to jython.
