Kotlin is-prefixed Boolean properties fail in derived queries with JPA property access

A Kotlin Boolean property whose name starts with is cannot be used in a derived query when the entity uses JPA property access.

Versions

Reproduced with:

• Spring Boot 4.1.0, Spring Data JPA 4.1.0, Hibernate 7.4.1.Final, Kotlin 2.3.21
• Spring Boot 4.0.7, Spring Data JPA 4.0.6, Hibernate 7.2.19.Final, Kotlin 2.2.21

Both setups use Java 17, H2, and kotlin-reflect.

./gradlew clean test printVersions
./gradlew clean test printVersions -PspringBootVersion=4.0.7 -PkotlinVersion=2.2.21

What happens

The entity uses property-access mapping:

@Entity
class PropertyAccessSample(
    @get:Id var id: Long = 0,
    @get:Column(nullable = false) var isActive: Boolean = false,
    @get:Column var isVerified: Boolean? = null,
)

The layers expose different names for the property:

findByActiveTrue() fails during query creation with a QueryCreationException caused by a PropertyReferenceException, because Spring Data's property model has no active property. findByIsActiveTrue() parses, but the generated JPQL references p.isActive; execution fails with a BadJpqlGrammarException whose cause chain contains Hibernate's UnknownPathException, because the JPA metamodel attribute is named active. The nullable findByIsVerifiedTrue() case produces the same failure for p.isVerified, so the mismatch is not limited to primitive boolean.

Expected behavior

findByIsActiveTrue() should resolve to the JPA metamodel attribute active. Because KotlinBeanInfoFactory intentionally exposes the property as isActive (spring-projects/spring-data-commons#3127), the names should be reconciled while resolving the JPA path rather than by adding an active alias in Spring Data Commons.

See #4305 for a proposed implementation.

Prior issues

I found related accessor and projection issues, but no duplicate covering derived-query paths: spring-projects/spring-data-commons#3127, spring-projects/spring-data-jpa#3771, spring-projects/spring-data-commons#3215, spring-projects/spring-data-commons#3249, and spring-projects/spring-data-commons#1947.
