JOIN Job should work without setting job parameter for required orders

Current Situation

The JITL job JobSchedulerJoinOrdersJSAdapterClass works with order parameters created by the split job. Since JITL-627 the order parameters are not considered in the correct way.

The join job does not work any more if the number of required orders is not set with the job parameters.

Desired Behavior

The join job should work without setting the parameter required_orders in the job.

Workaround

1. Add a job parameter to the join job.

Add a parameter with the name required_orders or <job_chain>_required_orders as a job parameter for the join job. The value is the number of splitted orders+1

Example:
The split job splits the main order into 2 child orders. The name of the job chain is job_chain1

required_orders=3

2. Alternatively Install a patch
There is a patch available for releases 1.13.7 and 1.13.8.
Please download from https://download.sos-berlin.com/patches/patch_forJITL-641_on_JS-1.13.7_8.jar and store the .jar file to $scheduler_home/lib/patches. Then restart JobScheduler Master.
