    Description

      When using spread-dot operator on an array in @CompileStatic annotated method the following error is raised:

      BUG! exception in phase 'instruction selection' in source unit 'ConsoleScript9' unexpected NullpointerException
      Caused by: java.lang.NullPointerException

      Reproducible example:

      import groovy.transform.CompileStatic
      
      @CompileStatic
      def foo() {
          new File("/").listFiles()*.name
      }
      
      foo()
      

      The problem doesn't occur when the operator is used on a list:

      import groovy.transform.CompileStatic
      
      @CompileStatic
      def foo() {
          new File("/").listFiles().toList()*.name
      }
      
      foo()
