>                 URL: https://issues.apache.org/jira/browse/GROOVY-11011
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>            Reporter: Eric Milles
>            Assignee: Eric Milles
>            Priority: Major
>              Labels: ClassFormatError
>
> 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, arg)
>             } else if (arg instanceof File) {
>                 file(name, 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.
