sentry-java: Failed to register sentrySpringFilter using Spring Boot 3 and Tomcat 10.1.15

Integration

sentry-spring-boot-starter-jakarta

Java Version

Version

6.32.0

Steps to Reproduce

Use a DockerFile with image ‘tomcat:10.1.15-jdk17-temurin-jammy’
Use a spring boot application v. 3.1.5
Specify maven dependency as following

<dependency>
    <groupId>io.sentry</groupId>
    <artifactId>sentry-spring-boot-starter-jakarta</artifactId>
    <version>6.32.0</version>
</dependency>

the following application.properties are defined:

sentry.send-default-pii=true
sentry.release=@project.version@
sentry.environment=local

There is no custom code or any sentry customization in our code
It runs fine using spring boot embedded tomcat
There are some strange warnings logged since updating spring boot to version 3 and changing sentry to the sentry-spring-boot-starter-jakarta package, but i do not think they are reason for the error

@adinauer Works like a charm! Thank you very much for the incredible fast response and the fix!

@gallusenrico @DisplayName522 we’ve just released 6.33.1 which should fix the issue. Please let us know if it helps.

Thanks for reporting, we’ll take a look. I’ve opened https://github.com/getsentry/sentry-java/issues/3068 so we can track.

What we’ve found out so far:

Starting with Spring-Boot 3.1.0 there is an exception instead of a log message, when a filter is already present in the ServletContext (https://github.com/spring-projects/spring-boot/pull/33911). I’ve not been able to get rid of the problem with 3.1.3. Only when using 3.0.12 and older as well as 3.2.0-RC1 and newer worked.

https://github.com/spring-projects/spring-boot/blob/dbe882aced8656b41d673b2542256c227bc528cd/spring-boot-project/spring-boot/src/main/java/org/springframework/boot/web/servlet/DynamicRegistrationBean.java#L113-L125

In case of an embedded Tomcat, as used when running bootJar, SentrySpringServletContainerInitializer is not being used. With a dedicated Tomcat however it is being used. This combined with SpringBootServletInitializer which I extended in SentryDemoApplication causes the duplicates to surface. I presume this has always been the case but only now results in an exception.

Our hunch says, embedded tomcat sets some flag differently to ignore src/main/resources/META-INF/services/javax.servlet.ServletContainerInitializer. ~~We’re trying to find out more here. Help appreciated~~.

It looks like starting with 3.2.x Spring adds filters first and only then SentrySpringServletContainerInitializer is called.

We’ve just opened https://github.com/getsentry/sentry-java/pull/3027 which seems to fix the problem. Needs some more testing before we release it.

Same here. Workaround for my was to downgrade the spring boot version to 3.1.3
