After initialyzing ICEpdf with a custom zoom level the first start of ICEpdf uses the right zoom level. Any later call of that viewer instance resets zooms level or other properties to default. In versions before 6.3 everything works fine.

Here is the code:

PropertiesManager props = PropertiesManager.getInstance();
props.clearPreferences();

// PropertiesManager props = new PropertiesManager(System.getProperties(),
// properties, ResourceBundle
// .getBundle(PropertiesManager.DEFAULT_MESSAGE_BUNDLE));

// load font cache to speed up startup time
String[] extraFontPaths = new String[] { System.getenv("windir")
+ "\\fonts\\" };
FontManager fontManager = FontManager.getInstance();
fontManager.readSystemFonts(extraFontPaths);
_logger.info("Viewer: Zoom-Werte werden gesetzt...");
// Einstellung der Zoom-Groesse aus den PuR-Eigenschaften
double dZoom;
try {
int iZoom = RechercheConfigManager.getInstance().getZoomViewer();
if (iZoom == 100) {
dZoom = iZoom * 0.0101;
} else {
dZoom = RechercheConfigManager.getInstance().getZoomViewer() * 0.01;
}
} catch (ValueNotFoundException e) {
dZoom = 1.40;
}
props.setBoolean(PropertiesManager.PROPERTY_SHOW_TOOLBAR_FORMS, Boolean.FALSE);
props.setBoolean(PropertiesManager.PROPERTY_SHOW_TOOLBAR_FORMS, Boolean.FALSE);
props.setDouble(PropertiesManager.PROPERTY_DEFAULT_ZOOM_LEVEL, dZoom);
props.setBoolean(PropertiesManager.PROPERTY_SHOW_UTILITYPANE_LAYERS,
Boolean.FALSE);
props.setBoolean(PropertiesManager.PROPERTY_SHOW_UTILITYPANE_BOOKMARKS,
Boolean.FALSE);
props.setDouble(PropertiesManager.PROPERTY_UTILITYPANE_THUMBNAILS_ZOOM,
0.3);

// Annotationen TRUE/FALSE:
props.setBoolean(
PropertiesManager.PROPERTY_SHOW_UTILITYPANE_ANNOTATION,
Boolean.FALSE);
props.setBoolean(PropertiesManager.PROPERTY_SHOW_UTILITY_SAVE,
Boolean.FALSE);
props.setBoolean(PropertiesManager.PROPERTY_SHOW_TOOLBAR_ANNOTATION,
Boolean.FALSE);
_ICEpdfController.setPropertiesManager(props);

FontPropertiesManager.getInstance().loadOrReadSystemFonts();
// new FontPropertiesManager(props, System.getProperties(), ResourceBundle
// .getBundle(PropertiesManager.DEFAULT_MESSAGE_BUNDLE));

// add interactive mouse link annotation support via callback
_ICEpdfController.getDocumentViewController().setAnnotationCallback(
new org.icepdf.ri.common.MyAnnotationCallback(_ICEpdfController
.getDocumentViewController()));

// Build a SwingViewFactory configured with the controller
SwingViewBuilder _ICEpdfViewBuilder = new MySwingViewBuilder(
_ICEpdfController, props);
