> Compilation fails when using JDK1.5 due to
> 1) no specification of language level
> 2) use of "enum" as identifier
> The language issue results in the use of the new StringBuilder class for string concatenation resulting in code that will not run on earlier JVMs.
> Dropping the langauge level will allow it to compile but warnings are generated due to the use of "enum" as an identifier; with 1.5 this becomes a reserved word
