FULL PRODUCT VERSION :
Reproduced on all of these:

Java(TM) SE Runtime Environment (build 1.9.0-ea-b57)
Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-ea-b57, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7600]

A DESCRIPTION OF THE PROBLEM :
I compile the following class (CompilerBug.java)

public class CompilerBug {
int var = 0;

public static void main(String[] args) {
new CompilerBug().new Inner();
}

public class Inner {
public Inner(Runnable r) {}

public Inner() {
this(() -> {
var = 1;
});
}
}
}

Compilation finishes without errors. However I see a VerifyError when running the compiled CompilerBug.class

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create file CompilerBug.java (see "source code" section):

2. Compile it:
javac CompilerBug.java

3. Run the compiled class:
java CompilerBug

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Compilation error on step 2 like it's reported by ECJ:

1. ERROR in C:\projects\Test\src\CompilerBug.java (at line 12)
this(() -> {
^^^^^
Cannot refer to 'this' nor 'super' while explicitly invoking a constructor

ACTUAL -
Compilation goes fine, but when compiled class is launched (step 3) the following error is displayed:

Exception in thread "main" java.lang.VerifyError: Bad type on operand stack
Exception Details:
  Location:
    CompilerBug$Inner.<init>(LCompilerBug;)V @3: invokedynamic
  Reason:
    Type uninitializedThis (current frame, stack[2]) is not assignable to 'CompilerBug$Inner'
  Current Frame:
    bci: @3
    flags: { flagThisUninit }
    locals: { uninitializedThis, 'CompilerBug' }
    stack: { uninitializedThis, 'CompilerBug', uninitializedThis }
  Bytecode:
    0000000: 2a2b 2aba 0003 0000 b700 04b1

        at CompilerBug.main(CompilerBug.java:5)

REPRODUCIBILITY :
This bug can be reproduced always.
