> Consider the following:
> {code:groovy}
> ['x'].toArray(new String[0])
> {code}
> This produces a bytecode sequence that includes a cast from {{String[]}} to {{Object[]}}.  javac for the same code omits the cast.
> {code}
>      9  iconst_0
>     10  multianewarray java.lang.String[] [44]
>     14  invokedynamic 0 cast(java.lang.String[]) : java.lang.Object[] [58]
>     19  invokeinterface java.util.Collection.toArray(java.lang.Object[]) : java.lang.Object[] [64] [nargs: 2]
> {code}
> Note: {{multianewarray}} vs {{anewarray}} was fixed by GROOVY-10031
