Dear All,
I experienced a strange behavior of Spring using Logback and SMTP appender. It seems, there is an incompatibility between the latest Spring version and Logback SMTP appender.
Logback file:
<?xml version="1.0" encoding="UTF-8"?>
<!--
https://howtodoinjava.com/spring-boot2/logging/profile-specific-logging/
https://howtodoinjava.com/spring-boot2/logging/profile-specific-logging/
-->
<configuration>
<include resource="org/springframework/boot/logging/logback/defaults.xml" />
<include resource="org/springframework/boot/logging/logback/console-appender.xml" />
<appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">
<smtpHost>...</smtpHost>
<to>...</to>
<from>...</from>
<subject>...</subject>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%date %-5level %logger{35} - %message%n</pattern>
</layout>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>
</appender>
<root level="INFO">
<appender-ref ref="EMAIL" />
</root>
</configuration>
Dependency for logback smtp:
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>

Comment From: robozb
so far the only solution was: to change log4j2
Comment From: philwebb
Devtools can sometimes cause classloader issues, you could try temporarily removing it to see if you still get the problem.

Dear @philwebb, Thanks but It didn't work :(
Comment From: robozb
I made a sample github project, I got the exception at this pure Springboot project as well: https://github.com/robozb/SpringBoot3LogbackSmtpAppenderError
Comment From: philwebb
A bit of debugging in the sample shows the real cause is the following:

That can be fixed by adding a mail dependency to the POM:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
The fact the actual cause isn't reported isn't great, I've opened #36645 to see if we can improve that.
Comment From: philwebb
I just noticed you have javax.mail:javax.mail-api in the comment above that listed your dependencies, you'll need to switch to Jakarta versions.
Comment From: robozb
You are my hero @philwebb :) Thank you so much!
Comment From: robozb
I can't force to show the full exception list How could you do that? Thanks!
Comment From: philwebb
@robozb Ahh yes, it's a fun little debug trick. I added an exception breakpoint for ModelHandlerException. That stopped me at AppenderModelHandler line 75. I then added a watch expression of oops.printStackTrace() and that got me to the real cause in the console.
