Executing a process that contains a Task with an SLA Due date is resulting in a duplicate timer creation with the following setting in kie-deployment-descriptor.xml:
 

        <environment-entry>
            <resolver>mvel</resolver>
            <identifier>new String ("true")</identifier>
            <parameters/>
            <name>AsyncMode</name>
        </environment-entry>

 
Note this will not have any functional impact on the process execution, but adds additional overhead to the timer subsystem.
