[logback-user] Upgrading Logback Classic from 1.3.8 to 1.3.9 causes ClassNotFoundException: ch.qos.logback.classic.spi.Configurator

[Ceki Gülcü]

Hi Christian,

The deprecated method ContextInitializer.configureByResource was removed
because it was preventing the decoupling of logback initialization from
JoranConfigurator class.

Downstream developers, for example Micronaut developers, can circumvent
this incompatibility problem by copying the code in the
ContextInitializer.configureByResource method into their project. This
should be a relatively easy exercise.

In any case, apologies for the inconvenience.

Best regards,
