Hi Paulo,
I must admit that making a URLConnection request from within select
looks a little funny, but I don't think it should cause a problem. I've
run the test you posted and I don't see the default proxy selector being
invoke. I only see the user defined selector. Can you provide more
information about what you are seeing? JDK version, any debugging
output/traces?
It may also be worth enabling HTTP logging,
-Djava.util.logging.config.file=logging.properties (see attached
logging.properties)
-Chris.
