------------------------------------

             Summary: SC: array instanceof guard and length or subscript
                 Key: GROOVY-11011
                 URL: https://issues.apache.org/jira/browse/GROOVY-11011
             Project: Groovy
          Issue Type: Bug
            Reporter: Eric Milles
            Assignee: Eric Milles


Consider the following:
{code:groovy}
@groovy.transform.CompileStatic
class FileTreeBuilder {
    def methodMissing(String name, Object args) {
        if (args instanceof Object[] && args.length == 1) {
            def arg = args[0]
            if (arg instanceof Closure) {
                dir(name, arg)
            } else if (arg instanceof CharSequence) {
                file(name, arg.toString())
            } else if (arg instanceof byte[]) {
                file(name, (byte[]) arg)
            } else if (arg instanceof File) {
                file(name, (File) arg)
            }
        }
    }
}
{code}

STC gives no errors for this, but there are 2 class format issues.  "args.length" is reporting bad type on operand stack and "if (arg instanceof CharSequence)" and subsequent guards are reporting improper class name "Ljava/lang/Object;" on the operand stack.
