/**
 * This tests the setting of reply timeouts using the RELATIVE_RT_TIMEOUT_POLICY
 * and the jacorb.connection.client.pending_reply_timeout property.
 * A problem existed where the policy value was longer than the property value,
 * the timeout was occurring according to the property value and the policy
 * value was ignored.  A fix was implemented to wait for the timer created
 * using the policy value to complete if the property value timed out first.
 * The tests cover the different circumstances where neither/both/either of
 * these QoS items are set.
