[SNMP4J] TestAgent and BaseAgent Example

[Frank Fock]

Hi Murali,

I know that I should have update SNMP4JAgent already to fix this
problem. Here is the fix (that I posted already on the list) which has
to be applied to MOScalar.java:

  private static boolean isVolatileByDefault(Variable value) {
    if (value == null) {
      return true;
    }
    switch (value.getSyntax()) {
      case SMIConstants.SYNTAX_COUNTER32:
      case SMIConstants.SYNTAX_COUNTER64: {
        return true;
      }
      default:
        return false;
    }
  }

SNMP4J 1.6 and the first beta of SNMP4J-Agent will be released
in a few weeks. These versions will then already prepared to support
SNMP4J-AgentX.

Best regards,
Frank
