+   <li>If using an IBM JDK at version 1.4 or higher within Eclipse,

+   several of the AspectJ projects will fail to build as checked out

+   solution is to add graphics.jar to the project classpaths... BUT

+   ant build script will pick up the contents of graphics.jar and
+   include it in the aspectj distribution (obvious clue, the size of
+   the built aspectjtools.jar doubles to about 10MB). Instead, from the 
+   Java Build Path properties page of the project, select "Add Library"
+   and add the JDK library. You now have to remove the JRE_LIB entry
+   from the project or Eclipse complains about duplicate jar files
