>             Project: Groovy
>          Issue Type: Bug
>            Reporter: Eric Milles
>            Priority: Minor

> Follow up from GROOVY-9151.  Consider the following Groovy script:
> {code:groovy}
> @groovy.transform.CompileStatic
> void greet(Object o = 'world', String s = o.toString()) {
>   print "hello $s"
> }
> greet()
> {code}
> NOTE: If the first parameter is changed to any type besides {{Object}}, the 
> script runs as expected.  So there must be some special handling for the 
> dynamic parameter type.
> When executed this script throws the following exception:
> {code}
> Exception in thread "main" java.lang.IncompatibleClassChangeError: Expected 
> static method java.lang.Object.toString()Ljava/lang/String;
