Description of problem:


When calling a sub-process using Reusable sub-process, and [Wait For Completion] = false.
The main (parent) process gets Completed once the sub-process is called, and sub-process contains a timer which will take some time before completion.

On the sub-process's completion, get "SessionNotFoundException" exception. 
Attaching the stacktrace as "error.log";
The process definitions are attached as "01360830-Reusable_Sub-process.zip"

This only happens when 1) using "Per-Process-Instance" runtime strategy  AND  2) set [Wait For Completion] = false for Reusable sub-process.

The tasks inside the sub-process seem all executed with no issue, the error happens when the sub-process finishes.


Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:

1) install clean bpms 6.0.2 and create a project in business-central
2) in business-central, import the 2 process def.  and build/deploy
3) in business-central, go to "Deploy - Deployments", remove the default "Singleton" deployment unit, create a new one with "Per_Process_Instance" strategy
4) start a parentprocess  instance, type something whatever you like as input data



Actual results:

all process instances finish with no error


Expected results:

error happens as in error.log
