Description

[code]
class VarArgs {
def method(Object... args)

{ println "method with Objects" }

def method(Integer... args)

{ println "method with Integer" }

}

def a = new VarArgs()
a.method(1, 2, 3, 4, 5)
[/code]

1/ The above code fails with the following exception:

Caught: groovy.lang.MissingMethodException: No signature of method: VarArgsMethod.method() is applicable for argument types:
(java.lang.Integer, java.lang.Integer, java.lang.Integer, java.lang.Integer, java.lang.Integer) values:

{1, 2, 3, 4, 5}

at VarArgsMethod.invokeMethod(VarArgs.groovy)
at VarArgs.run(VarArgs.groovy:14)
at VarArgs.main(VarArgs.groovy)

2/ If you change the method signatures to be Object[] and Integer[] respectively, the code still fails with the same error.

3/ If you change the method signature from Object... (or Object[]) to be a type which is not a super type of Integer (f.e. String... the
code will correctly run).
