JobExecutor.waitTimeInMillis being ignored

[jsilva]

Hello, everyone.

I'm trying to change the default value for the JobExecutor's waitTimeInMillis property, but my jobs are being retried immediately.

I'm using Activiti 5.15.1 and this is the relevant configuration:

<bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
    <!– … –>
    
    <property name="jobExecutor">
       <bean id="jobExecutor" class="org.activiti.engine.impl.jobexecutor.DefaultJobExecutor">
          <property name="waitTimeInMillis" value="60000" />
       </bean>
    </property>
  </bean>
‍‍‍‍‍‍‍‍‍‍‍

I've found that the reason why this happens comes from the code block at org.activiti.engine.impl.jobexecutor.AcquireJobsRunnable:68:

if (jobsAcquired < maxJobsPerAcquisition) {
    // …
} else {
    millisToWait = 0;
}
‍‍‍‍‍‍‍

So I have three questions:

1. Could someone please explain to me the reason why someone would want a job to execute immediately when the maximum number of jobs has been acquired?

2. What would you suggest to wait before retrying a job? Somehow overriding a FailedJobCommandFactory?

Thanks for your time.

@Sridhar_B,  Activiti 5.12 is really old (more than 2 years), and considering the comment added by @jsilva, maybe migrating to a newer version will help you.
