Description

When compiling a function with an argument of the same name as the function, and the function includes a closure, I get a "can't have abstract method in non-abstract class" message.

bug17Interface.groovy:

interface bug17Interface {
void vars(Set vars)
}

bug17Abstract.groovy:

abstract class bug17Abstract implements bug17Interface {
void vars(Set vars) { [].each

{ it.vars(vars) }

}
}

but17.groovy:

class bug17 extends bug17Abstract { }

typing "groovyc bug17.groovy" gives:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, bug17.groovy: 1: Can't have an abstract method in a non-abstract class. The class 'bug17' must be declared abstract or the method 'vars' must be implemented.
@ line 1, column 1.
class bug17 extends bug17Abstract { }
