            Description

            A user has reported the following issue:

            We came across an architectural problem in IcePDF. As you can see from the stack below and the corresponding coding there are UI manipulations done from a custom thread. Java defines Swing not to be thread safe. Therefore doing so might cause problems.

              We could change ice.pilots.pdf.ThePilot so that it uses SwingUtilities.invokeAndWait(Runnable) or possibly SwingUtilities.invokeLater(Runnable), so that Swing is accessed in a thread-safe manner.

              Update ICEbrowser pilot and did a little testing. The Swing work should all be happening on the awt thread.
