Ceki Gulcu commented on LBCORE-159:
-----------------------------------
Let us keep in mind that the appendLoopOnAppenders in Logger assumes that
appenders do *not* throw exceptions. Consider a set up where a logger, say L,
has appenders A and B attached to it. If the present patch is applied, how
would we deal with the situation where appender A throws an exception? Should
we still try to invoke the doAppend method on B? If we decide to invoke B and
it also throws an exception, should we percolate the exception generated by A
or that generated by B?
I would like to see an attempt to answer these questions before the patch is
applied.

>
> When logging some events the application needs to be informed that the
> publishing of the event failed. Currently, AppenderBase and
> UnsynchronizedAppenderBase catch and handle all exceptions making it
> impossible to use any of the out-of-the box Logback appenders in these
> situations. This is particularly important when performing auditing and
> sending the events to a database, JMS queue, socket, etc. as the application
> would want to fail the current operation if it cannot be audited.
