Java API - index out of bounds error on simple call

[SamahSohrab607228]

I'm having a strange issue with the Java API calling to get JobHeaders. 
Here is my code

OpenObject openObject = new OpenObject(new UC4ObjectName(jobName), true, true)
connectionService.sendRequestAndWait(openObject)
UC4Object uc4_object = openObject.getUC4Object()

connectionService.sendRequestAndWait(new CloseObject(uc4_object))

and here is my stack trace

java.lang.IndexOutOfBoundsException: Index: 12, Size: 4

This function works for hundreds/thousands of other jobs/workflows, but this workflow is giving this error. The header tab is valid when you open it via the client, and the workflow is running without issue.

I made a duplicate of this workflow and I still get the same error, but I can't see anything special about this workflow.
