my springboot version is 3.0.9. when I use Lininx shell 'kill -15 pid' to kill my java application, it reported some exception like these:

This error doesn't happen every time, it just happens occasionally, and I don't even know how to reproduce this problem. I am very certain that this class 'org.springframework.boot.web.server.GracefulShutdownCallback' exists.
Thanks for help.
Comment From: mhalbritter
Hello,
Spring Boot 3.0.9 isn't OSS supported anymore. Please upgrade to a supported version and if it still happens, please share a minimal reproducer (it's okay if it doesn't happen every time). I'll then re-open this issue.
Could also be a duplicate of https://github.com/spring-projects/spring-boot/issues/40096.
Thanks!
Comment From: kingston-csj
My Jdk version is 17. I have upgraded my springboot version to 3.2.5， but the problem still exists. I don't know the specific reproduction method, but one thing is certain: if the program is closed immediately after starting, there will be no problem. But if I restart after a few hours, the following error is reported:

Could you please try with Spring Boot 3.2.11?
Comment From: kingston-csj
Could you please try with Spring Boot 3.2.11?
OK, I'll give it a try. I'll run the program for a few hours and see the results tomorrow.
Comment From: kingston-csj
I upgraded springboot's version to 3.2.11. After running the program for 13 hours, I just restarted it and there won't be any errors. I will observe for a few more days. Many thanks.
Comment From: kingston-csj
This error occurred in the Amazon Linux environment, and it has never occurred in Windows or Ubuntu. I am not sure if it is related to the operating system.
Comment From: philwebb
@kingston-csj are you saying you're now observing the error again? Or does your previous comment about an upgrade fixing it still stand?
Comment From: kingston-csj
Sorry, I didn't express clearly. I just wanted to supplement the operating environment that previously reported errors. After the upgrade, there will be no problems on any operating system. @philwebb
Comment From: kingston-csj
Today i found this error occured agin after running for a week. My os is amazon linux 2023. My other operating systems, Windows and Ubuntu, do not experience this error. The error messages in versions 3.2.5 and 3.2.11 are not exactly the same. The 3.2.5 version is shown as https://github.com/spring-projects/spring-boot/issues/42923#issuecomment-2446361233, which has a timeout block ‘ Failed to shut down 1 bean with phase value 2147482623 within timeout of 30000ms’.
The 3.2.11 version ,however, occured 'NoClassDefFoundError' exception without timeout block. Here's the exception stack info.

The 3.2.5 version ,however, occured 'NoClassDefFoundError' exception without timeout block.
Is the stacktrace shown above from 3.2.5 or from 3.2.11?

Yes， I have upgraded springboot's version to 3.2.11. The stacktrace shown above is 3.2.11
Comment From: mhalbritter
Thanks.
I guess there's a bug somewhere in our loader.
You could try to switch to the old uber jar implementation and see if that works: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.2-Release-Notes#nested-jar-support
Comment From: kingston-csj
Ok, do I only need to update my pom.xml like this?
I need to wait until the next version maintenance and take some time to check the running status of the version. Thanks.
Comment From: mhalbritter
Yeah, that should do it.
Comment From: kingston-csj
Ok, I'll have a try
Comment From: kingston-csj
After modifying the parameters, the error still exists. I am curious if it can be seen from the packaged file that my configuration has been modified and taken effect.
Here's my pom.xml file

That still looks like the new loader to me:
at org.springframework.boot.loader.launch.LaunchedClassLoader.loadClass(LaunchedClassLoader.java:91)
The classic loader's class loader is org.springframework.boot.loader.LaunchedURLClassLoader.
Comment From: kingston-csj
When I found this exception, I saw the following dependencies on my local Maven， the springboot plugin's version was not 3.2.11. I'm not sure if these versions can support this parameter “loaderImplementation”.
Perhaps my project uses Maven's modularity, and the spingboot of the submodule does not inherit the boot of the parent pom.xml correctly.
Now I have manually added version parameters, I will observe for a while longer.
Many thanks.

Configuring the classic loader should work with Spring Boot 3.2.x, but it's no longer supported. Please upgrade to Spring Boot 3.3.6 or 3.4.0.

The project has been put into operation externally. I am concerned that introducing too new a version may have potential issues. At present, it is only a reboot error and has no significant impact on the business. For now, I just ignore it. I hope there will be a small version in the future that can fix LaunchedClassLoader.

Understood. We'll certainly try to fix the problem if we can figure out what it is. To do that, I think we'll need a minimal sample that reproduces it. Please let us know if you manage to create one.

I try to create a temp branch and remove all my business code. I will let it run for a few days and see if the error still exists.

I removed most of bussiness logic code and kept all the external resouce access, such as AmazonS3, MongoDb, Redis connections. I ran it a few times but cannot reproduced the exception. The server is probably not busy enough to trigger gc? On the other hand, the complete project will still encounter errors when restarted.

I think that's the first time that the possibility that it's related to GC has been raised. Why do you think that may be the case?
Comment From: kingston-csj
I was just guessing casually, because it takes a long time to run and the business logic is quite active before it triggers
Comment From: wilkinsona
For GC to be the cause, I would expect it to be related to the use of soft references. There is some such usage in the loader but it's minimal and I haven't noticed any problems when inspecting the relevant code. I think we still need a reproducer to get to the bottom of this one, unfortunately.
