A DESCRIPTION OF THE PROBLEM :
Strange behaviour of java compile with the final modifiers.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Try to compile class Test from the source code field.

Removing ANY (absolutely any: from Test, from Inner, or from while cycle) final modfier from the example causes testcase to compile well.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should compile well.
ACTUAL -
Compilation error: variable boo might have already been assigned

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Compilation error: variable boo might have already been assigned

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public class Test
{
    final Inner boo;

    public Test()
    {
        Inner too = new Inner( 0, 0 );
        while( "a".equals( "b" ) )
        {
            final int aa = 1;
            too = new Inner( 2, 3 );
        }
        boo = too;
    }
    
    class Inner
    {
        final int a;
        final int b;
        
        Inner( int a, int b )
        {
            this.a = a;
            this.b = b;
        }
