NullPointerException when no invoker proxy bindings configured

When no invoker proxy bindings are configured, org.jboss.metadata.BeanMetaData.getInvokerBindings() returns a NullPointerException. This is caused by the fix for JBAS-4444. org.jboss.metadata.ConfigurationMetaData.getInvokers() used to return a zero-length array when no bindings were configured but it now returns a null value which BeanMetaData.getInvokerBindings() does not properly handle:

public Iterator getInvokerBindings()
{
if (invokerBindings == null)
{
// See if there is a container default invoker name
String[] defaultNames = configuration.getInvokers();
if (defaultNames.length > 0) // Line 263 NPE
{
invokerBindings = new HashMap();
for (int count = 0; count < defaultNames.length; count++)

{ invokerBindings.put(defaultNames[count], getJndiName()); }

}
else

{ // Use the hard-coded defaults defaultInvokerBindings(); }

}

return invokerBindings.keySet().iterator();
}

Changing line 263 to if(defaultNames!=null && defaultNames.length()>0) would eliminate the NPE.
