Gary Gregory commented on LOG4J2-2023:
--------------------------------------
Using custom separators was discussed and rejected. The fix here will be to use
getName() if getCannonicalName() returns null.
> Use a class' canonical name instead of name to create its logger name

> Use a class' canonical name instead of name to create its logger name.
> Say you have loggers built with Classes for which {{getName()}} give you:
> - {{com.example.app.A}}
> - {{com.example.app.A$AS1}}
> - {{com.example.app.A$AS2}}
> - ...
> - {{com.example.app.A$ASN}}
> Before 2.9.0: You you set the root logger to {{WARN}} and
> {{com.example.app.A}} to {{INFO}}, then you get {{INFO}} events for A but you
> do not get {{INFO}} messages from {{AS1}}, {{AS2}}, and so on. There is no
> way to set all {{A$ASx}} loggers to the same level at the same time.
> In 2.9.0 now, converting a Class to a logger name uses
> {{getCannonicalName()}} such that the logger names are:
> - {{com.example.app.A}}
> - {{com.example.app.A.AS1}}
> - {{com.example.app.A.AS2}}
> - ...
> - {{com.example.app.A.ASN}}
> When you set {{com.example.app.A}} to {{INFO}}, then you get {{INFO}} events
> for {{A}}, {{AS1}}, {{AS2}}, and so on.
