James.Mailet: RemoteDelivery: Exception caught in RemoteDelivery.run()

[li...@gmail.com]

i am using James Mail Server 2.3.1

i am getting this exception:

INFO  James.Mailet: RemoteDelivery: Exception caught in RemoteDelivery.run()
java.lang.NumberFormatException: null
    at java.lang.Integer.parseInt(Integer.java:446)
    at java.lang.Integer.parseInt(Integer.java:519)
    at
org.apache.james.transport.mailets.RemoteDelivery$MultipleDelayFilter.accept(RemoteDelivery.java:160)
    at
org.apache.james.mailrepository.AvalonSpoolRepository.accept(AvalonSpoolRepository.java:157)
    at
org.apache.james.transport.mailets.RemoteDelivery.run(RemoteDelivery.java:1111)
    at java.lang.Thread.run(Thread.java:713)

in

RemoteDelivery:
public boolean accept (String key, String state, long lastUpdated,
String errorMessage) {
  if (state.equals(Mail.ERROR)) {
    //Test the time...
    int retries = Integer.parseInt(errorMessage);   <<<< exception
occurs here
              
    // If the retries count is 0 we should try to send the mail now!
    if (retries == 0) return true;
  ...


which is called from here

AvalonSpoolRepository:
public synchronized Mail accept(SpoolRepository.AcceptFilter filter)
  ...
  if (mail == null || !filter.accept (
                         mail.getName(),
                         mail.getState(),
                         mail.getLastUpdated().getTime(),
                         mail.getErrorMessage()))
  ...

it appears that

  mail.getErrorMessage()

can return null sometimes.

that means that the code in RemoteDelivery.accept() needs to handle that
condition.

does anyone know if this is fixed in JAMES v2.3.2?
