>         Environment: JVM 1.8.0_102, MacOS 10.11.6

> If a call to logger.info() invokes the toString() method on one of its parameters, and
that toString() method invokes another method which has another, nested logging call, then
the output of the outer call is mangled.
> This can be quite confusing as the nested logging may be conditional, or at DEBUG level,
etc.
