Error description
When you run a heritage human service after upgrading IBM Business Process Manager (BPM) to V8.5.6 or V8.5.7, the service fails. In the server SystemOut.log file, you see an exception like the following exception: Ä4/9/16 22:25:13:124 CDTÜ 000001d2 EJBWorkflowMa E CWLLG0594E: An exception occurred while initializing the runnable thread.

Local fix
Problem summary
IBM BPM V8.5.0 introduced an objectId property in the metadata of a business object to identify the business object. This property is automatically filled when a business object is created. When navigation in a heritage human service from a coach step returns to the same coach step?either by using wires or a Stay On Page event?the coach is not completely refreshed; only the changed data applies. IBM BPM V8.5.6 enhanced the logic to use the objectId property to determine which data changed. This enhanced logic is used only for process applications that use the system toolkit in V8.5.6 or a later releases. However, this logic fails because the objectId is not set when you have an IBM BPM deployment environment earlier than V8.5.0 with active instances and you perform the following steps: 1. Upgrade the IBM BPM deployment environment to V8.5.6 or V8.5.7. 2. Install a new snapshot of your process application that uses the new system toolkit version. 3. Migrate active instances to that new snapshot. 4. Run a heritage human service.
Problem conclusion
A fix that automatically initialized the objectId property when it is not yet set 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 Central: 1. Select IBM Business Process Manager with your edition from the product selector, the installed version to the fix pack level, and your platform, and then click Continue. 2. Select Text, enter ?cumulative fix?, and click Continue.
