Quarkus 3.17.1+ does not like 'get' methods on Panache (Kotlin) Entities

[pschyma]

Describe the bug

I updated a project from 3.17.0 to 3.17.2 and started receiving exceptions in building and testing related to Hibernate bytecode enhancing:

    java.lang.RuntimeException at QuarkusTestExtension.java:628
        Caused by: java.lang.RuntimeException at AugmentActionImpl.java:355
            Caused by: io.quarkus.builder.BuildException at Execution.java:124
                Caused by: java.lang.reflect.UndeclaredThrowableException at ExtensionLoader.java:862
                    Caused by: java.util.concurrent.ExecutionException at FutureTask.java:122
                        Caused by: org.hibernate.bytecode.enhance.spi.EnhancementException at EnhancerImpl.java:131
                            Caused by: java.lang.StringIndexOutOfBoundsException at Preconditions.java:55

I traced it down to Hibernates Enhancer [1]. Starting from Quarkus 3.17.1 the Hibernate version used does not seem to like entities like

@Entity
class Entity(@Id var id: Long, var year: Int, var january: Double, var february: Double, ...) : PanacheEntityBase {
  operator fun get(month: Month) = ...

  companion object : PanacheCompanionBase<Entity, Long> {
   fun get(year: Int): Entity = ...
  }
}

The enhancer does not like both get methods.

Expected behavior

Quarkus builds the project without any issues.

Actual behavior

No response

How to Reproduce?

No response

Output of uname -a or ver

Linux

Output of java -version

21

Quarkus version or git rev

3.17.1+

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

Gradle 8.11.1

Additional information

I'm not sure whether this is a Quarkus or Hibernate issue; but since it's also occurring on Quarkus/ Panache companion objects, I decided to start here.

Could you provide a reproducer? Preferably in Java if it's reproducible in pure Java.

If it's a pure Hibernate ORM issue, probably a good idea to try to reproduce it with plain https://github.com/hibernate/hibernate-test-case-templates/tree/main/orm/hibernate-orm-6 . If you can't, a Quarkus reproducer is fine.

From what I can see, it looks like an Hibernate ORM issue but I will let @yrodiere confirm once we have a reproducer.

Thanks!

I could reproduce it with just Hibernate ORM: https://hibernate.atlassian.net/browse/HHH-18903

[geoand]

Is #44863 related in any way?

[mbladel]

Yep @geoand, this is also caused by the new check - though a slightly different case (method simply named get()), causing a different exception. I've already linked the Hibernate issue created by @pschyma as related to https://hibernate.atlassian.net/browse/HHH-18904, we should address both when reviewing the check logic.

Thanks again @mbladel!
