MethodParameters are not filled in for synthetic captured local variables

FULL PRODUCT VERSION :
Java version " 1.8.0-ea "
Java(TM) SE Runtime Environment (build 1.8.0-ea-b90)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b32, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Mac OS X 10.7.5 Build 11G63

A DESCRIPTION OF THE PROBLEM :
For implicit, synthetic constructor arguments to an anonymous inner class, the generated MethodParameters attribute is corrupt.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the source file below:

$ javac -parameters ParameterNames.java

Now run javap:

$ javap -c -s -p -l -v ParameterNames\$1.class


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I was expecting that the MethodParameters attribute for the constructor of ParameterNames$1 was well-formed, with a length of two parameters.

javap is expected to decode those.


ACTUAL -
  ParameterNames$1(ParameterNames, java.lang.String);
    descriptor: (LParameterNames;Ljava/lang/String;)V
    flags:
    Code:
      stack=2, locals=3, args_size=3
         0: aload_0
         1: aload_1
         2: putfield #1 // Field this$0:LParameterNames;
         5: aload_0
         6: aload_2
         7: putfield #2 // Field val$message:Ljava/lang/String;
        10: aload_0
        11: invokespecial #3 // Method java/lang/Object. " <init> " :()V
        14: return
      LineNumberTable:
        line 6: 0
      MethodParameters: length = 0x5
       02 00 0A 80 10
                                   ^^^^ More bytes should be here


REPRODUCIBILITY :
This bug can be reproduced always.
