To see this, uncomment this line in regression test StringConvertTest.sh:

    #cmd print "(Object)($classname.x3)"

x3 is an array. The above print command should print something like:
   [LStringConvertTest$JJ2;@7bd9f2

which is what System.out.println(x3) would print.

Instead, it prints something like:
    instance of StringConvertTest$JJ2[2] (id=276)
