thank you for your reply Ceki, we also believe that logback design in this
way, but in our case logback stop our application from successfully launch,
I added some details in the following section and you may be able to
reproduce this issue

we configure all the logback configurations in the `logback-spring.xml`
file like this

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>
                %d{dd-MM-yyyy HH:mm:ss.SSS} %magenta([%thread])
%highlight(%-5level) %logger %M %line - [traceID: %X{X-B3-TraceId}] -
[RequestId: %X{RequestId}] - [ClientId: %X{ClientId}] - %message
%exception{full} %n
            </pattern>
        </encoder>
    </appender>
    <springProfile name="local,dev">
        <root level="DEBUG">
            <appender-ref ref="console"/>
        </root>
    </springProfile>


as you can see from the above code snippet we create an appender and attach
this to local, dev spring profile. after this, we try to create a new
spring profile called dev2 and activate this profile by the following
configuration in `application.yml` file

profiles:
  active: dev2


so we have three environment property file in our project

after we try to start our application, it failed to start without any error
message, we only can see the following message no other output

and as I said in the previous email we can fix this by adding the `dev2`
env profile name to the  logback configuration file like this

<springProfile name="local,dev,dev2">

at this point, we are not sure whether we encounter this issue, is it
because of our configuration or is it an existing issue of logback?

Regards,
yaer
