DMI: Invocation of toString on an array (DMI_INVOKING_TOSTRING_ON_ANONYMOUS_ARRAY)

The code invokes toString on an (anonymous) array. Calling toString on an array generates a fairly useless result such as [C@16f0472. Consider using Arrays.toString to convert the array into a readable String that gives the contents of the array. See Programming Puzzlers, chapter 3, puzzle 12.
