Note that even Sun breaks compatibility if you go from their 1.3 javac
to 1.4. <http://java.sun.com/j2se/1.4/compatibility.html>
 * If a serializable inner class contains explicit references to to
 its class object, then the computed value of the serial version UID
 for the class will be different in J2SE 1.3 and J2SE 1.4. The
 difference is due to the fact that the computation of the serial
 version UID is sensitive to modifications made in the javac compiler
 between J2SDK 1.3 and J2SDK 1.4.

 To avoid this problem affecting your applications, we recommend that
 you add an explicit serial version UID to your serializable classes.
 You can use the serialver tool to obtain the serial version UID of
 classes compiled with the J2SDK 1.3 javac compiler.
Basically saying, always use the same compiler to compile your classes
or break serialization. Sigh. I haven't found documentation of the
precise changes or how their new javac generates synthetic method names,
etc.
