             Summary: CLONE - Compiler writes extra cast for Type[] to Object[]
                 Key: GROOVY-10035
                 URL: https://issues.apache.org/jira/browse/GROOVY-10035
             Project: Groovy
          Issue Type: Improvement
          Components: bytecode
            Reporter: Eric Milles
            Assignee: Eric Milles


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
