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>
  </dependency>

Devtools can sometimes cause classloader issues, you could try temporarily removing it to see if you still get the problem.

I made a sample github project, I got the exception at this pure Springboot project as well:
https://github.com/robozb/SpringBoot3LogbackSmtpAppenderError

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.

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.

I can't force to show the full exception list How could you do that? Thanks!

@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.
