Logging leftover?

[bsideup]

Hi.

I tried 0.11.13 and I get a lot of "connection reset by peer" errors in the log. The best part is "test" log message:

rsocket-java/rsocket-core/src/main/java/io/rsocket/internal/ClientServerInputMultiplexer.java

Line 103 in 9f6fbcc

LOGGER.error("test", t);

Can it be a leftover from #467?
