Saving work item results in Long-running op prohibited msg

I am trying to change the workflow state of a work item via the following methods:

WorkItemWorkingCopy.setWorkflowAction(String)
WorkItemWorkingCopy.save(null)

The exception below is logged to stdout. Why is this message being logged when ThreadCheck.prohibitLongOps() is never called by my code and the system property "disallow.server.ops.on.ui.thread" is NOT set?
