    Description

      • It has been observed that users can't run Process Simulation on a complex BPMN2 process from Business Central (using "Run Process Simulation" feature from the Web Designer) , if the process has got a complex series of XOR and AND gateways , which result in numerous combination of possible paths for the flow.
      • When we try to start the simulation it does not work and results the following message in the screen "Unable to perform simulation:undefined" .
      • It does not log anything relevant for process simulation in server.log file , even after running the entire server with DEBUG logging enabled.
      • Thread dumps collected during the time when the issue takes place suggests as if the stack trace was going in an infinite loop. Although it doesn't result in stackoverflow but keep spinning.

          Bug - A problem that impairs or prevents the functions of the product. RHBPMS-4013 [GSS] (6.3.z) Process Simulation fails if the process contains a series of complex XOR and AND gateways and numerous branches

          • Critical - To be worked on immediately following BLOCKER issues.

          Bug - A problem that impairs or prevents the functions of the product. RHBPMS-4082 [GSS](6.3.z)After the simulation fails the server becomes unresponsive and it does not even respond to shutdown requests

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
