Not logback (which seems an excellent library BTW) but plain ol' java.util.logging. Netty adapts to what's available https://github.com/netty/netty/blob/4.1/common/src/main/java/io/netty/util/internal/logging/InternalLoggerFactory.java#L19 .

I'm going to quiet the stack dumps I observe in test_socket only, treating them for now as a side effect of the way we keep making and tearing things up when testing. There are two loggers: one producing at SEVERE, the other at WARNING, which I'll set to OFF and SEVERE respectively.

I suspect there are real causes here we could fix, along with the hang I regularly experience, but I'd need to know more about Netty and sockets -- which I'd like to.
