Can't compile Lambda referencing final variable initialized on constructor

FULL PRODUCT VERSION :
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Linux 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
When a Lambda expression defined as a class instance references a final variable that is initialized only inside a constructor, but without calling "this." before the variable, the compiler throws a compilation error.

With the "this." before the variable, the compiler works fine.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See provided source code to compile.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
Compiling 2 source files to /home/bruno/javabug/build/classes
/home/bruno/javabug/src/FooBar.java:14: error: variable foobar might not have been initialized
        System.out.println(foobar); // throws compilation error
1 error

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
/**
 * @author bruno.borges@oracle.com
 */
public class FooBar {

    private final String foobar;

    public FooBar() {
        foobar = "foobar";
    }

    private final java.util.function.Function ds = n -> {
        System.out.println(this.foobar); // compiles successfuly
        System.out.println(foobar); // throws compilation error: "variable foobar might not have been initialized"

        return foobar;
    };

}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
The reference to the variable must be preceded with "this." or else the compiler throws a compilation error.
