Description

(from the mailing list):

I wrote:

– script –
c1 = new Class[]

{ Exception.class, Throwable.class }

c2 = new Class[]

{ IllegalStateException.class }

println (c1)
println (c2)
[c1, c2].each

{println(it)}

– output –
[Ljava.lang.Class;@14da8f4
[Ljava.lang.Class;@fd68b1
Incorrect arguments to closure: CommandLine4$_run_closure1@10a2d64.
Expected: [class java.lang.Object], actual: [class java.lang.Exception,
class java.lang.Throwable]

John Wilson responded:

It's a bug

The closure code is getting confused into thinking that you are calling it with Exception.class, Throwable.class as parameters.
