NullPointerException in 11.0.6 Compiler

    Details

    • Subcomponent:
    • CPU:
      x86
    • OS:
      os_x

      Description

      A DESCRIPTION OF THE PROBLEM :
      When trying to compile my project, the compiler NPE's and dies inside FlowAnalyzer.visitApply (line 1235).

      REGRESSION : Last worked in version 11.0.6

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Unfortunately this error came up in the process of compiling a large project, and is not easily reproducible.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The code should have compiled, or at least provided an error informing me of what code is wrongly written.
      ACTUAL -
      The compiler outputs a NullPointerException and dies:
                             An exception has occurred in the compiler (11.0.6). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.
                             java.lang.NullPointerException
