            Description

            When using the ICEPdf API in the AIX environment if a font in the PDF is missing the thread that calls the ICEPdf API to generate the images goes into a waiting thread; and remains in the waiting state.
            Expected behavior : A exception needs to be thrown so that the caller of the API is aware of the issue.

                Here is AIX supports input: (essentially, they are saying that we need input from ICEPDF team on what their code is waiting on, and that this does not appear to be an AIX specific issue)
