org.hibernate.internal.SessionImpl present in hibernate-core 5.6.15.Final doesn't implement jakarta.persistence.EntityManager
https://github.com/hibernate/hibernate-orm/blob/5.6/hibernate-core/src/main/java/org/hibernate/internal/SessionImpl.java

Error:

Caused by: java.lang.IncompatibleClassChangeError: Class org.hibernate.internal.SessionImpl does not implement the requested interface jakarta.persistence.EntityManager

Steps I checked,

excluded default hibernate-ehcache included explicitly and excluded hibernate-core

    implementation ("org.grails.plugins:hibernate5"){
      exclude module: "hibernate-ehcache"
    }
    implementation ("org.hibernate:hibernate-ehcache:5.6.15.Final"){
      exclude module: "hibernate-core"
    }

Now the hibernate dependencies

grails-datastore-gorm-hibernate5-9.0.0-M2.jar
hibernate-commons-annotations-5.1.2.Final.jar
hibernate-core-jakarta-5.6.15.Final.jar
hibernate-ehcache-5.6.15.Final.jar
hibernate-validator-8.0.2.Final.jar
hibernate5-9.0.0-M2.jar

Starting application without hibernate-core throws below error

Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cache.ehcache.internal.SingletonEhcacheRegionFactory
        at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

SingletonEhcacheRegionFactory not present in hibernate-core-jakarta

Including hibernate-core higher version hibernate-core-6.6.4.Final.jar which has jakarta.persistence.EntityManager implementation throws below error

implementation group: 'org.hibernate.orm', name: 'hibernate-core', version: '6.6.4.Final'

https://github.com/hibernate/hibernate-orm/blob/6.6/hibernate-core/src/main/java/org/hibernate/internal/SessionImpl.java

Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cache.ehcache.internal.SingletonEhcacheRegionFactory

It is only available upto hibernate-core-5.6

org.hibernate.cache.ehcache.internal.SingletonEhcacheRegionFactory lives in org.hibernate:hibernate-ehcache:5.6.15.Final.

@anil-subudhi If you remove the following does it resolve the NoClassDefFoundError?

    exclude module: "hibernate-ehcache"

I am going to work on the hibernate-core exclude on #951

[anil-subudhi]

@jamesfredley Sorry for the late reply

If I remove exclude ehcache from hibernate5, the SingletonEhcacheRegionFactory issue resolves but it throws

Caused by: java.lang.IncompatibleClassChangeError: Class org.hibernate.internal.SessionImpl does not implement the requested interface jakarta.persistence.EntityManager

as hibernate-ehcache includes hibernate-core:5.6.15 and org.hibernate.internal.SessionImpl not present in 5.6.15 version

https://github.com/hibernate/hibernate-orm/blob/6.6/hibernate-core/src/main/java/org/hibernate/internal/SessionImpl.java

implementation ("org.grails.plugins:hibernate5"){
      //exclude module: "hibernate-ehcache"
}

 +--- org.hibernate:hibernate-ehcache:5.6.15.Final
|    |    +--- org.jboss.logging:jboss-logging:3.4.3.Final -> 3.6.1.Final
|    |    +--- org.hibernate:hibernate-core:5.6.15.Final

Explicitly adding hibernate-ehcache like doesn't resolve SingletonEhcacheRegionFactory

    implementation ("org.grails.plugins:hibernate5"){
      exclude module: "hibernate-ehcache"
    }
   
     implementation ("org.hibernate:hibernate-ehcache:5.6.15.Final"){
      exclude module: "hibernate-core"   // exclude 5.6.15 version
    }

Hi @anil-subudhi

Explicitly adding hibernate-ehcache like doesn't resolve SingletonEhcacheRegionFactory

That is surprising!
What is the error message?

For testing purposes, could you try:

implementation 'org.grails.plugins:hibernate5:9.0.0-M2', {
    exclude group: 'org.hibernate', module: 'hibernate-ehcache'
}
runtimeOnly 'org.hibernate:hibernate-ehcache:5.6.15.Final', {
    // exclude javax variant of hibernate-core 5.6
    exclude group: 'org.hibernate', module: 'hibernate-core'
}
runtimeOnly 'org.jboss.spec.javax.transaction:jboss-transaction-api_1.3_spec:2.0.0.Final', {
    // required for hibernate-ehcache to work with javax variant of hibernate-core excluded
}

[anil-subudhi]

Thank you @matrei for quick reply,

org.jboss.spec.javax.transaction:jboss-transaction-api_1.3_spec:2.0.0.Final

Resolves the SingletonEhcacheRegionFactory, without jboss-transaction-api_1.3_spec it throws NoClassDefFoundError

Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cache.ehcache.internal.SingletonEhcacheRegionFactory

OK @anil-subudhi, thanks for the confirmation!
This will be documented as required when using org.hibernate:hibernate-ehcache in Grails 7 with Hibernate 5.
