http://issues.apache.org/bugzilla/show_bug.cgi?id=43651 Summary: NPE without manually clearing image cache Product: Fop Version: 0.94 Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P2 Component: images AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I use FOP in a stand alone application (Eclipse RCP) for Export (PDF, PS) AND Print (direct awt print) from the same fop-sources. One and the same FopFactory is used per application run. The AWT-Print renderer is set up by: PrintRenderer renderer = new PrintRenderer(printerJob); renderer.setUserAgent(userAgent); userAgent.setRendererOverride(renderer); Each transformation type (print or export) works for its own. Doing an export followed by a print transformation (or the way around) of the same source results in a NullPointerExeption for each Image. Please see the stack trace below. In other words: If you start with an export you can always do a successfull export, but never an awt-print. If you start with an awt-print you can always do a successfull awt-print but never an export. Manually clearing the ImageCache solves the problem. As the API of org.apache.fop.image.ImageFactory.clearCaches() points out, this must be an issue. The URLs does not change between the fop-runs. Its protocol is OSGI-specific and shouldn't be the source of the problem. Similar URLs work perfect in all other parts of the application and with clearing the ImageCache too.
