>             Project: Commons Lang
>          Issue Type: Bug
>          Components: lang.reflect.*
>    Affects Versions: 3.5
>            Reporter: Eickvonder
>
> Since release 3.5 and due to the changes of LANG-1115 an ArrayStoreException occurs on
MethodUtils.invokeMethod if using varargs arguments and smaller types than the method defines
(e.g. int vs long).
> {code}
>   @Test
>   public void testMethodUtilsInvokeMethodVarArgs () throws Exception {
>     MyObject object = new MyObject ();
>     MethodUtils.invokeMethod (object, "doSomething", 1);
>   }
>   public static class MyObject {
>     public void doSomething (long... args) {
>       System.out.println ("doSomething");
>     }
>   }
> {code}
> throws 
> {code}
> java.lang.ArrayStoreException
> 	at java.lang.System.arraycopy(Native Method)
> 	at org.apache.commons.lang3.reflect.MethodUtils.getVarArgs(MethodUtils.java:497)

> {code}
> In 3.4. a NoSuchMethodException had been thrown, but in 3.5 the code now finds the matching
method but fails then with above exception.
