body: <p>I've just installer the ASM Eclipse Plugin (and restarted), which give an improved Bytecode Outline, and I can use it for the JRE classes, but looking at my own code, I get the error message in the title.</p>
  
  <p>My java project is on Build Automatically, and I my source files do not have errors, and I can see the class files in the Default output folder defined in the Java Build Path of the Project's properties.</p>
