      Description

      This sad little snippet, when compiled as bug.java, crashes javac in a way I haven't been able to find documented yet. I've worked it down to it's essential components.

      class mug
      {
         void m()
      {
         bug b=new bug();
      }
      }

      Here is the result:
      hagen@mile[89]: javac bug.java
