      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_25"
      Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
      Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7601]

      A DESCRIPTION OF THE PROBLEM :
      Upon compiling the source code given below, the compiler crashes and gives a NullPointerException. Strangely, I could build a complete day until the problem started occuring.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile the source code given below with javac Bug.java

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Plain compilation error that mentions the non inclusion of the class HashMap or the non existence of the two argument constructor
      ACTUAL -
      Failure executing javac, but could not parse the error:
      An exception has occurred in the compiler (1.8.0_25). 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.
