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

             Summary: 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


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;
