    • Introduced In Version:

      Description

      Take the following code:

      import java.lang.annotation.*;

      interface Consumer {
          void method(String s);
      }

      class LambdaInInitBlock {
          {
              Consumer fn1 = (@TA String i) -> {};
          }
      }

      @Target(ElementType.TYPE_USE)
      @interface TA {}


      This works correctly if the lambda is in a method/constructor. But with the lambda in the initializer block, javac 1.8 gives:

      An exception has occurred in the compiler (1.8.0_05). 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.
