-------------------------------
Resolution: Cannot Reproduce
> SC: Script method with default arguments throws IncompatibleClassChangeError
> ----------------------------------------------------------------------------
>
> Key: GROOVY-9193
> URL: https://issues.apache.org/jira/browse/GROOVY-9193
> 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;
