[Apiman-user] Logger exception

[Marc Savy]

The default logger seems to work fine for me, e.g.

apiman-gateway.logger-factory=io.apiman.common.logging.
DefaultDelegateFactory

Double check you didn't accidentally null the entry out by overwriting it
later in your config.

For SLF4J, the WAR implementation doesn't have the logger on the classpath
by default. You can do it manually, but it's a bit of a hassle and is only
a small addition, so I've added it and it will be in the next release:
