These 3 tests contain declaraion of classes with identical names (class A, class B,
class C). When compiled, the .class files are placed in the same directory, so these
class files from one of these tests can overwrite them from the other test.

As result, this can cause an error because the test could be run with a wrong
B.class (A.class, C.class) if regression testbase is running 2 or more times.

There are other Serialization tests that have the same problem:

When I run regression tests using Javatest on a 1.5 workspace
for the first time, all java/io/Serializable tests pass.

However, if I then run the tests again (without deleting the
files created by the previous test run) I get these test failures:

* java/io/Serializable/GetSuidClinitError.java
* java/io/Serializable/BadSerialPersistentField.java
* java/io/Serializable/FinalFields.java
* java/io/Serializable/PartialClassDesc.java
* java/io/Serializable/WriteObjectMemory.java
# java/io/Serializable/ExplicitCNFException.java
# java/io/Serializable/DefaultDataEnd.java
# java/io/Serializable/SurvivePrematureClose.java
* java/io/Serializable/BadSerialVersionUID.java
* java/io/Serializable/LookupInterfaceDesc.java
# java/io/Serializable/OptionalDataEnd.java
* java/io/Serializable/DefaultReadObjectCNFException.java

Besides the duplicate classes A, B, C mentioned above, Foo is also
duplicated.

It's important to fix these because engineers will spend a lot of time
chasing down non-bugs in the code they changed until they learn that
"Serializable failures are ignorable."
