Java Development Environment Release Notes

In addition to the information here, see our demos.

Since this release is based on Sun's Java2 SDK, v 1.2, it in general contains the same known bugs and fixed bugs. For details, see Sun's Java Bugs Web Site.

General Release Notes

• The javadoc program automatically creates HTML documentation for Java classes from the source code. The HTML files that it creates make use of various decorative images; these can be found in the /usr/java/images directory.

Native Code Development Release Notes

See our Native Code documentation for an introduction to working with native code.

jdb Release Notes

• To evaluate a variable in your Java program:
  
  
  • you must have compiled the Java source file with the -g option to javac, and
    
    
  • if evaluation of a local variable is required, the current thread must be stopped at a point where the variable is live; in other words, the variable must have been given a value, and there must be a possibility that that value will be used before it is changed.
  
  Unless both of these are true, you will get the message "<not in scope>".
  
  
• Currently, you can only evaluate symbols (for example, print xyz or print this.abc). You cannot evaluate expressions.
  
  
• It is not possible to print the elements of multidimensional arrays.
  
  
• If you use the "up" and "down" commands to move around in the call stack of a suspended thread, the "step", "next", and "return" commands will no longer operate with respect to the selected stack frame as they have in previous releases; they now always operate with respect to the last frame in the call stack.
  
  
• When running under jdb, it is not possible to set breakpoints in native methods.
  
  
• When debugging an applet, using the "Restart" item in the appletviewer's menu may cause some applets to function incorrectly. If you encounter this problem using jdb, you must quit and restart jdb instead.
