Here is an excerpt from the Sametime 7.5.1 SDK development guide :
J9 JCL Desktop
Lotus Sametime Connect 7.5 for Windows and Linux platforms uses a compacted, custom Java Runtime Environment known as the J9 JCL (Java Class Libraries) Desktop. While this pared down J9 Java Runtime Environment enables a smaller footprint for the Sametime Connect Client, the J9 does not contain the full number of Java classes included in the standard 1.4.2 or 1.5 Sun JVM. For example, some of the classes not contained in the J9 JVM are AWT & Swing classes, which are used for graphical user interface (GUI) objects in Java applications. These packages are not part of the J9 JVM because SWT is the
default Eclipse platform GUI, SWT uses the operating system to create native graphics, and SWT is lighter (i.e. less resource intensive) than either AWT or Swing. Accordingly, developers may encounter issues when utilizing a toolkit that references a class or package (such as AWT or Swing) that is not included in the J9 VM.
