The regression test

    test/java/io/Serializable/defaulted/GetFieldWrite.java

is bad because it depends on unspecified details of the handling of
class literals by the compiler. In Tiger those details are changing
for two reasons: (1) the default -source and -target are changing, and
(2) The VM will be providing durect support for class literals, making
the synthetic support infrastructure generated by the compiler
unnecessary.

In addition, the handling of class literals can change from compiler
to compiler in a way that affects the default SVUID.
