@CompileStatic/@TypeChecked unexpected NullpointerException compiler bug

    Details

    • Type: Bug
    • Status: Closed
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 2.4.6
    • Fix Version/s: 2.4.7
    • Component/s: Compiler
    • Labels:
      None
    • Environment:
      Windows, jdk1.8.0_60

      Description

      Those code produce compiler bug exception (see below) when @CompileStatic or @TypeChecked is used :

      @CompileStatic
      class KeywordApiMain {
      static main(args) {
      Optional.of("MH370").orElseThrow(

      { -> new RuntimeException() });
      }
      }

      @CompileStatic
      class KeywordApiMain {
      static main(args) {
      Optional.of("MH370").orElseThrow { -> new RuntimeException() }

      ;
      }
      }

      Those code just produce the expected behaviour when compiled and run without the annotation. The workaround is simplifying the code to this :
      class KeywordApiMain {
      static main(args) {
      Optional.of("MH370").orElseThrow

      { new RuntimeException() }

      ;
      }
      }

      The compiler output :
      Error:Groovyc: BUG! exception in phase 'instruction selection' in source unit '-------\XXXX.groovy' unexpected NullpointerException
