Hi,

if you append array's which contains null values to an EqualsBuilder instance, 
a NPE is thrown. This causes troubles in the ArrayUtils.isEquals(Object[], 
Object[]) method as well because it uses the EqualsBuilder class.

To duplicate: execute this code:

Object[] array1 = new Object[] {"1", null, "2"};
Object[] array2 = new Object[] {"1", null, "2"};
new EqualsBuilder().append(array1, array2).isEquals();

and you'll get this Exception:

java.lang.NullPointerException
at org.apache.commons.lang.builder.EqualsBuilder.append(EqualsBuilder.java:513)

kind regards,
Maarten Coene
