VM throws error "java.lang.VerifyError" when I use a class which is compiled with "-target 1.4" but it works fine if the class is not compiled with "-target 1.4" option.

How to reproduce
----------------
1. javac -target 1.4 A.java B.java
2. java A


** A.java B.java is attached

In javac version 1.4, wrong byte code is generated in <init> method in certain situations. In this example, method <init> in class A$1$Class_B accesses instance field before calling any instance initialization method. This is not allowed according to the VM spec 2nd edition 4.8.2.
