RHPAM-4296 describes a situation with WIH and exception handling sub-process that can lead to a situation where the engine is unable to abort the process instance that hit this issue. While the fix from this JIRA addresses the root cause of the issue, this only applies to newly created process instances. Instances created in an environment without the fix still cannot be aborted.

The intent of this JIRA is to make the code more robust and to allow to abort such process instances.
