All I can say is that it's nothing to do with the use of a ServiceLocator,
and that it works for me.
Can you look at the DeobfuscatorBuilder generated by ValidationTool? (if
you configured annotation processing in Eclipse, look at the .apt_generated
folder, otherwise use the "apt" tool from the JDK (or javac) with the "-s"
argument to write the generated source to disk) Does it look OK wrt
client/server-classes mappings?
Alternately, could you set a breakpoint in
com.google.web.bindery.server.ResolverServiceLayer#resolveClientType and
try to understand why it chooses MyBaseProxy for a MyChild1 object instead
of MyChild1Proxy?
