Warning about failing to index Spring class on reload

[fedinskiy]

Describe the bug

I have an app, which uses several Spring extensions. When I run in a Dev Mode and do a reload (manually or a by adding a new file) there is a warning in a logs.

This warning emerged after update from 3.11.0 to 3.12.3

Expected behavior

No warnings during reload

Actual behavior

-07-31 12:07:06,391 INFO  [io.qua.dep.dev.RuntimeUpdatesProcessor] (Aesh InputStream Reader) Restarting as requested by the user.
2024-07-31 12:07:06,400 INFO  [io.quarkus] (Quarkus Main Thread) app stopped in 0.008s
<...>
2024-07-31 12:07:06,530 WARN  [io.qua.arc.pro.BeanArchives] (build-12) Failed to index org.springframework.aot.hint.annotation.Reflective: Class does not exist in ClassLoader QuarkusClassLoader:Deployment Class Loader: DEV for app-1.0.0-SNAPSHOT@2d2d94bf

How to Reproduce?

1. Create an app:

 mvn io.quarkus.platform:quarkus-maven-plugin:3.13.0:create -DprojectGroupId=my-groupId -DprojectArtifactId=app -DprojectVersion=1.0.0-SNAPSHOT -DpackageName=org.my.group -DquarkusRegistryClient=false -DplatformVersion=3.13.0 -Dextensions=quarkus-rest,spring-boot-properties,spring-di,spring-security,spring-web && cd app # spring-data-jpa also seem to be affected

2. Run in a dev mode: mvn clean quarkus:dev
3. Wait for the app to start and reload it by pressing s or by adding a new class

Output of uname -a or ver

6.7.3-200.fc39.x86_64

Output of java -version

Java version: 21.0.1, vendor: Eclipse Adoptium

Quarkus version or git rev

3.13.0

Build tool (ie. output of mvnw --version or gradlew --version)

Apache Maven 3.9.6 (bc0240f3c744dd6b6ec2920b3cd08dcc295161ae)

Additional information

No response

It seems, that 3.12.0 is the first version which is affected, since 3.11.3 is not

[geoand]

Hm...

When I start the application (before any live reload, I see):

2024-08-02 13:57:05,839 WARN  [io.qua.agr.dep.AgroalProcessor] (build-18) The Agroal dependency is present but no JDBC datasources have been defined.
2024-08-02 13:57:05,945 WARN  [io.qua.hib.orm.dep.HibernateOrmProcessor] (build-22) Hibernate ORM is disabled because no JPA entities were found
2024-08-02 13:57:05,967 WARN  [io.qua.dat.dep.dev.DevServicesDatasourceProcessor] (build-36) Unable to determine a database type for default datasour

And these warnings make sense as you have not added any JDBC related extensions

[fedinskiy]

@geoand try to drop "spring-data-jpa" from the creation command (ie make it look like this: mvn io.quarkus.platform:quarkus-maven-plugin:3.13.0:create -DprojectGroupId=my-groupId -DprojectArtifactId=app -DprojectVersion=1.0.0-SNAPSHOT -DpackageName=org.my.group -DquarkusRegistryClient=false -DplatformVersion=3.13.0 -Dextensions=quarkus-rest,spring-boot-properties,spring-di,spring-security,spring-web && cd app)
The warnings you mentioned will be gone, but the reflection warning will stay

[geoand]

In that case I see the following on reload:

WARN  [io.qua.arc.pro.BeanArchives] (build-9) Failed to index org.springframework.aot.hint.annotation.Reflective: Class does not exist in ClassLoader QuarkusClassLoader:Deployment Class Loader: DEV for app-1.0.0-SNAPSHOT@37a3eb7f

@aureamunoz ^

[fedinskiy]

@geoand yes, that is the one I meant. I will change the description to make it more clear

[aureamunoz]

I've just seen this one. The org.springframework.aot.hint.annotation.Reflective wasn't included in our quarkus-spring dependency but it has been in #42895 so it will be released with 3.14.2 and the warning should be gone

@aureamunoz #42895 is merged and present in 3.14.2, I tested this reproducer with 3.14.4 and the issue is still present. Will you have a look?

[aureamunoz]

Hi, I just looked at it and I can't reproduce it. Everything works fine for me, I don't have any errors. Do you have the project in question?

I only saw it in CI when I bumped Quarkus to 3.14.4. Let me try it locally and report back.

[michalvavrik]

Here are steps to reproduce:

mvn io.quarkus.platform:quarkus-maven-plugin:3.14.4:create -DprojectGroupId=my-groupId -DprojectArtifactId=app -DprojectVersion=1.0.0-SNAPSHOT -DpackageName=org.my.group -DquarkusRegistryClient=false -DplatformVersion=3.14.4 -Dextensions=quarkus-rest,spring-boot-properties,spring-di,spring-security,spring-web && cd app

mvn clean quarkus:dev

Wait for the app to start and reload it by pressing s or by adding a new class.

Oups!

[aureamunoz]

It appears that the @Reflective annotation is part of a new specific Spring Framework dependency, which comes from the Spring Experimental AOT package. This dependency is not currently included in any of our Quarkus Spring* dependencies.

Initially, I added this class to be included in the quarkus-spring-aop module because I didn’t notice the aot distinction. The package name for the class is very similar to the AOP module's and doesn’t include the word "experimental," which led to the confusion.

To resolve this, a new Quarkus Spring Experimental project/artifact/dependency will need to be created to support this functionality.

[aureamunoz]

false alarm, it can be included in the quarkus-spring-core
