  • Closed as program error.

Error description

  • he problem appears to be with ToolKit.getImage(URL). Using Java
1.4.2 and 1.5, every time this call is made, the applet jar is
re-downloaded from the server. Sun's workaround involves using
ImageIcon and BufferedImage to create the customer cursor.

Sun's URL for this bug is at:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4990532

Local fix

Problem summary

  • Using JRE 1.4 versions, when the applet viewer is initialized,
the viewer jar file is downloaded
into the client machine for each toolbar icons. This is a big
impact on the applet performance.This is indeed a JDK bug, for
details, http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4912
903

The problem is fixed in CM83 FP4

Problem conclusion

  • To workaround the JDK bug, create a urlconnection object to load
the image icon and set the useCaches to true for this
urlconnection instance.

Temporary fix
