      Description

      FULL PRODUCT VERSION :
      java version "1.7.0_06"
      Java(TM) SE Runtime Environment (build 1.7.0_06-b24)
      Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode)


      ADDITIONAL OS VERSION INFORMATION :
      Linux devaccarch 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

      A DESCRIPTION OF THE PROBLEM :
      I'm trying to rewrite some classes from Weld with my own implementations. I don't want to touch the existing code, so I copied the classes into my own project, keeping all the dependencies to the original.

      One of the classes that I want to replace is a nested private static class that I moved into a file with the name of the container class + $ + inner, and made it public. This has worked fine in other occasions.


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      The setup is a little bit difficult to describe, but simple im maven. I haven't found an attachment feature here, so I gzipped the minimized maven project and base64-ed it.

        To unpack and run do the following:
      1. put the text in the source field into a file called javac-npe-example.tar.gz.base64
      2. base64 -d javac-npe-example.tar.gz.base64 > javac-npe-example.tar.gz
      3. tar xzf javac-npe-example.tar.gz
      4. cd dummy
      5. mvn clean install

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      the compiler should either just do it's work or report a specific error message
      ACTUAL -
      javac fails with a NullPointerException

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      An exception has occurred in the compiler (1.7.0_06). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.
