Error description

• When you run a process with a linked process activity that has
  an implementation that contains ad hoc activities, you get a
  NullPointerException in at least one of the following scenarios:
  
  - You run the process on IBM Process Center and the hierarchy of
  linked processes spans across processes defined in toolkits for
  which you last modified the top-level process and the deepest
  nested process but kept a process in between unchanged.
  
  - You use a dynamic process defined as the implementation of a
  linked-process activity.
  
  You see the following warning in the SystemOut.log of the
  server:

Local fix

Problem summary

• When the definition of the preconditions of an ad hoc activity
  is to be looked up, the diagram of a nested linked process is
  not properly looked up, potentially because it's using the
  process definition from an incorrect toolkit version. For a
  linked-process activity with a dynamic linked process, the
  diagram of that dynamic linked process is not considered.
  

Problem conclusion

• A fix will be included in an upcoming IBM Business Process
  Manager (BPM) V8.5 cumulative maintenance vehicle.
  
  To determine whether the cumulative fix is available and
  download it if it is, complete the following steps on Fix

  group, IBM Business Process Manager with your edition from the
  WebSphere options, All as the installed version, and All as the
  platform, and then click Continue.
