[SNMP4J] Why does org.snmp4j.smi.Null.java:getInt( ) return the syntax

[David Goodenough]

If no value is returned for an OID (so a Null object is used) if you ask it
for its integer value rather than getting an exception you get the number
5.  This is the value of the syntax for a null value, and seems rather 
unrelated to the "nullness" of the object.  Surely the value should be 0 or
an exception should be thrown.  The syntax of the object is of course
already available through the method getSyntax.  The same applies to toLong.
