> ArrayUtils.addAll(T[] array1, T... array2) does not handle mixed array types very well.
> The stack trace for 
> Number[] st = ArrayUtils.addAll(new Integer[]{1}, new Long[]{2L});
> starts:
> java.lang.ArrayStoreException
> 	at java.lang.System.arraycopy(Native Method)
> 	at org.apache.commons.lang3.ArrayUtils.addAll(ArrayUtils.java:2962)
> which is not all that obvious.
> It would be a lot clearer if the method threw an IlegalArgumentException or similar.
