Description Philip Borlin

All JDK/JREs are Windows JDK/JREs from Sun.  I am using the stable build of
Eclipse from February 14, 2002.

When I tried to change my JRE from 1.3.0 to 1.4.0 and import the corresponding
rt.jar for 1.4.0, I noticed that javax.swing.AbstractAction outline does not
contain the method actionPerformed(ActionEvent ae).  When I compile my code I
get the error: "The method actionPerformed(java.awt.event.ActionEvent) is
undefined for the type javax.swing.AbstractAction".  This is huge since a good
portion of my program will not compile because I (correctly) assume all over my
code that AbstractAction has the actionPerformed(ActionEvent ae) method.

I have tried creating new projects and the same behavior is exhibited.  This
problem does not occur when I use either 1.3.0 or 1.3.1.

This is due to a change in the rt.jar between 1.4 and 1.3.x. In 1.3.x abstract classes have a 
abstract methods for methods inherited by their interfaces. This is when the target is 1.1 vms. 
However, the JDK1.4 libraires are compiled to target 1.2 VMs and these abstract methods are 
removed.
This is a duplicate of 10701. You can fix the errors by setting the Compiler compliance 
level to 1.4 instead of 1.3. Go to:
Preferences>Java>Compiler>JDK Compliance>Compiler 
compliance level. Set this value to 1.4. Then it will recompile your code and it should fix all 
errors related to this problem.
