> For development of an avro-based transport for remote OSGi services I had=
 to wrap & unwind transport-level exceptions into proper exceptions thrown =
to a client. One such scenario is accessing a disconnected/dead endpoint, w=
hich should be a detectable condition. This works fine with the SaslSocketT=
ransceiver (where my wrapper can properly detect the IO Exception), but not=
 with Netty which hiccups with an internal NPE.
> Generally speaking any transport-level and remote-endpoint exceptions mus=
t not only be clearly detectable (either directly by client code or wrapper=
 infrastructure around avro) but also distinguishable from another.
