Description

expression

new org.codehaus.groovy.runtime.MethodClosure(object,"myMethod")

never makes closure with support for variable arguments, even if myMethod is defined as:

public String myMethod(Object[] args)

{ ... }

I have located the problem in Groovy source code.
In MethodClosure.java doCall is defined as:

protected Object doCall(Object arguments) {
...
}

but lang.groovy.Closure constructor turns on variable argument support only if type of last argument in doCall is Object [].

A workaround is to use expression:

new Closure(object) {
public String doCall(Object[] args)

{ return object.myMethod(args); }

}
