             Summary: [Broker-J] Error about negative credit used value is reported into broker logs
                 Key: QPID-8322
                 URL: https://issues.apache.org/jira/browse/QPID-8322
             Project: Qpid
          Issue Type: Bug
          Components: Broker-J
    Affects Versions: qpid-java-broker-7.1.3, qpid-java-broker-7.0.7
            Reporter: Alex Rudyy
             Fix For: qpid-java-broker-7.0.8, qpid-java-broker-7.1.4


When client credit for bytes or/and messages is set to "infinite credit",  the invocation of {{WindowCreditManager#restoreCredit}}  always tries to deduct used values for bytes or/and messages, whilst the used values are not increased on invocation of {{WindowCreditManager#useCreditForMessage}}. As result, this leads to the following error reported into broker logs: 
{noformat}
ERROR [IO-/127.0.0.1:45904] (o.a.q.s.p.v.WindowCreditManager) - Bytes credit used value was negative: -5742
{noformat}
The reported "error" is completely harmless and can be ignored.
