transceiver can be shared between clients/threads?

from the constructor of SpecificRequestor, it does not seem to have
restrictions,
but after I share the same transceiver between clients, it gave errors.
I looked into the code, it seems it does have some per-instance state info,
so I guess
a transceiver can not be shared between clients,

could you please confirm?

Thanks
Yang

Thanks Doug and Scott.

I found that it *could* be because that I closed the transceiver, which of
course would lead to errors if some other threads are still using it.
let me do more tests to make sure

Transceiver and Requestor should actually be thread-safe.

What version of Avro are you using?  Can you provide a test case that
shows how this fails?  If so, please file a bug report.

Thanks,

Doug

I do not believe the current implementation is thread-safe.
