Could not initialize JfrConnectionCreatedEvent #1767

Bug Report

Current Behavior

Since the latest Spring 2.5.0 Update we observe a Lettuce/Redis Error on every single Request, which basically breaks our App. It is in the Stacktrace below.

We use the default Property based Autoconfiguration. Spring 2.4.5 worked perfectly fine. Has something changed that i am not aware of?

Stack trace

Unhandled Exception in Controller, returning: HTTP 500 INTERNAL_SERVER_ERROR
org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class io.lettuce.core.event.connection.JfrConnectionCreatedEvent

Expected behavior/code

It should work fine like it did with Spring 2.4.5.

Environment

spring-boot-starter-data-redis: 2.5.0

Any help/hint is greatly appreciated

Can you attach the full stack trace of Could not initialize class io.lettuce.core.event.connection.JfrConnectionCreatedEvent? What JVM version ($ java -version) are you using?

Lettuce should not attempt loading JFR classes unless your JVM version ships with JFR support.

Need a Minute to check the JVM Version we use in our container. But i do know we use Java 11 if thats enough.

EDIT: Redacted some lines retrospectively for security reasons

I am a team member of alfagun and we use open-jdk 11.0.10 as buildpack

mp911de · 2021-06-07T14:28:46Z

This looks as if there was a dependency conflict. JfrEventRecorder was introduced with Lettuce 6.1, and the same version ships JfrConnectionCreatedEvent. Can you spot earlier occurrences of JfrConnectionCreatedEvent?

Right now, there's no way to disable JFR event publishing unless using an older Java 8 runtime. I wonder whether it would make sense to add a config flag (system property) to disable JFR by configuration.

PhilippAllstadt · 2021-06-07T14:41:22Z

Sadly, there are no occurrences of JfrConnectionCreatedEvent in other dependencies or elsewhere only in Lettuce as i could see. So do you mean there is no configuration yet to disable JFR via system properties or elsewhere ? Maybe we have to switch back to Java 8 runtime for the moment.

mp911de · 2021-06-08T07:51:06Z

Likely rolling back to Lettuce 6.0.x comes with the least impact. For a Java 8 rollback, you'd need to roll back to a version earlier than JDK 8 update 262 which can impose security concerns.

Alfagun74 · 2021-06-08T08:49:28Z

I just double checked, we only have "lettuce-core 6.1.2.RELEASE" imported by Spring-Data-Redis in our Project.
We're going to stay at Java 11 and exclude it manually and import a 6.0.X version for now.
Thank you for your fast and good help so far @mp911de. Do you know what may cause this Error in 6.1.2?

Alfagun74 · 2021-06-08T09:00:15Z

With manual downgrade to 6.0.4 it works for now

mp911de · 2021-06-08T12:40:14Z

Without additional details, I cannot really tell what causes the problem. I haven't seen such issues in other integrations (e.g. when building Spring Data Redis or Spring Data Redis examples on Java 16).

mp911de · 2021-06-09T07:45:55Z

I introduced a system property to disable JFR support. I'd like actually to dig further here to find out about the cause. Can you update your application to perform some Redis interaction right at the startup of your application? Moving the interaction phase to the startup would give us an opportunity to have improved means of logging instead of relying on the web request logging.

PhilippAllstadt · 2021-06-09T13:43:48Z

Thank you very much for the support, we will include the updated version and try out the new flag. So we could try to interact via crud repository right due to the startup phase of the app.

Alfagun74 · 2021-06-24T08:41:33Z

Hi @mp911de I cant seem to set the property. How & where do you set it the correct way? It doesn't get recognized in my Application YAML and also wont be recognized when we set it in PostConstruct in our Spring App.

mp911de · 2021-06-24T08:50:43Z

The property is a system property. Spring Boot's application properties are not system properties. If you do not have access to system properties I suggest setting the system property in your main method before invoking SpringApplication.run(…).

Alfagun74 · 2021-06-24T09:14:17Z

Tysm! @mp911de

thesoundofsilent · 2021-08-03T14:30:11Z

@Alfagun74 Use the same code but fail to reproduce your issue, is there any other setting to reproduce the same error?

tawAsh1 · 2021-09-09T20:55:17Z

I'm still investigating, but it is possible that this error occurs when running on OpenJ9 JVM environment where jdk.jfr.Event can be loaded.

vishnuprakash-thoughtworks-sde · 2021-12-14T04:03:38Z

hi @Alfagun74 @mp911de do we know the root cause for this issue. we are also facing the same issue in our spring boot app (version 2.5.0). For us the issue is happening when App Dynamics agent is enabled.

mp911de · 2021-12-14T07:46:01Z

For us the issue is happening when App Dynamics agent is enabled.

You might want to reach out to the App Dynamics folks and let them help you with investigating what's going on.

I wasn't able to reproduce the issue at all.

vishnuprakash-thoughtworks-sde · 2021-12-15T02:47:24Z

thanks for the reply @mp911de . what is the impact of disabling JFR events in lettuce?

armanaaquib · 2022-02-26T06:34:21Z

Hello @vishnu-kprakash , Could you please tell how did you solve the problem? We are also getting the same error after enabling App Dynamics agent.

vishnuprakash-thoughtworks-sde · 2022-02-28T04:21:14Z

We took help from app dymanics team, they have made some changes in the agent configuration which resolved the issue

brettalcox · 2022-03-11T16:33:02Z

@vishnu-kprakash can you provide any detail on what the agent configuration changes were? was it agent config provided by the user? or bundled into a new version of the agent itself?

brettalcox · 2022-03-17T20:22:16Z

For visibility, adding --add-reads=jdk.jfr=ALL-UNNAMED to your JVM args will resolve the issue. TBD if this is something that needs to be permanent or addressed in future agent release.

EvertonSA · 2022-08-08T19:31:15Z

as matter of documentation, follow what --add-reads=jdk.jfr=ALL-UNNAMED does:

Flight Recorder collects data as events. An event has a time stamp, duration and usually an application-specific payload, useful for diagnosing the running application up to the failure or crash.

The compiler and runtime option --add-reads $module=$targets adds readability edges from $module to all modules in the comma-separated list $targets. This allows $module to access all public types in packages exported by those modules even though $module has no requires clauses mentioning them. If $targets is set to ALL-UNNAMED, $module can even read the unnamed module.
