body: <p>Is the java 1.4 projects compatible with Java 7?</p>
  
  <p>any known issue from anybody.
  In my case, when I use a class which was compiled using 1.4 (javap -verbose, major version:48) with Java6 it works fine. 
  But the same class with Java 7 code resulting in null pointer</p>
  
  <p>any ideas appreciated</p>
  
  <p>Thanks</p>
