Incorrect "variable might not have been initialized"

Sun's 1.4 javac gave me a "variable might not have been initialized" error on the code
below ... when it shouldn't have.

I don't have 1.5 installed. Could someone try it on 1.5 for me?

Code:

public class Test120
{
  public static void main(String[] args)
  {
    boolean retain ;
    long physicalId ;
    String ref ;
    if (retain = (physicalId = 1) > 0 &&
                 (ref = String.valueOf(physicalId)) != null)
      System.out.println(ref) ;
  }
}

1.4 javac output:

Test120.java:10: variable ref might not have been initialized
      System.out.println(ref) ;
                         ^
1 error

If Test120 works on 1.5, try this one:

public class Test121
{
  public static void main(String[] args)
  {
    Long id ;
    boolean retain ;
    long physicalId ;
    String ref ;
    if (retain = (id = new Long(1)) != null &&
                 (physicalId = id.longValue()) > 0 &&
                 (ref = String.valueOf(physicalId)) != null)
      System.out.println(ref) ;
  }
}

Lastly, this one works on 1.4 but not 1.2, so Sun seems to be making progress in this
area:

public class Test122
{
  public static void main(String[] args)
  {
    boolean retain ;
    String ref ;
    if (retain = 1 > 0 && (ref = System.getProperty("user.home")) != null)
      System.out.println(ref) ;
  }
}

Thanks.
