Thanks Jörg,
I created an account but have run into some http:500s and what-not from jira
while creating my account. I'll create the issue when I get all this stuff
sorted out.
The second question I have, semi-related, is how would you guys suggest doing
generational (ie cross-model-version) testing?
What I'd like to do is have tests like this:
public static class TestFixture{
public static class MyModel{ //v1
Public int x;
Public int y;
}
//And attempt to deserialize (using our moderately customized xstream
serializer) it as
public static class MyModel{ //v2
Public int x;
Public int y;
Publix int z;
}
//in something like this
@Test
public void
when_we_added_an_extra_int_field_for_feature_1234_we_didnt_break_anything_because_our_deserialization_flow_is_so_nifty(){
//setup
OurSerializerThatDelegatesToXStream serializer =
testHarness.provideSerializer();
//act
String serialized = serializer.serialize(makeVersion1OfMyModel());
MyModel myModelV2 = serializer.deserialize(serialized);
//assert
assertThat(myModelV2.z).followsProperDomainLogic();
}
}
But of course Javac is going to complain about 2 'MyClass'es.
Any suggestions?
I was thinking about trying using 2 different canonical names (so MyClass1 and
MyClass2), and then add an entry to the aliasMap as part of the setup logic to
tell XStream that MyClass1 is-a MyClass2.
But since that doesn’t involve nearly enough overly complex code, the other
thing I was thinking of doing is copy-pasting class files around and then
manually loading via some stupidly sophisticated mechanism. With a couple extra
ant targets I could probably even make this bearable.
Thanks for any help,

You're absolutely right. Can you open a JIRA ticket to track the issue, please?
Simply follow instructions at http://xstream.codehaus.org/issues.html
Cheers,
Jörg
Sad to say, but 2 hours earlier, and it would already have been part of the new
release :-/
