I took my application that runs in a wildfly 35 container(the bitnami/wildfly:35) and upgraded the container to wildfly 36(bitnami/wildfly:36).  The places in my pom.xml that reference versions of components supplied as provided wildfly have versions updated to match what shipps with wildfly 36.  These would be things like hibernate, infinispan etc. Initially I didn't update my persistence.xml to be 3.1, it was left at 2.1.   After the exception happened, I tried converting it to use 3.1 This made no difference but here's what my persistence.xml looks like now <?xml version= "1.0" encoding= "UTF-8" ?> <persistence version= "3.1" xmlns= "[https://jakarta.ee/xml/ns/persistence]"               xmlns:xsi = "[http://www.w3.org/2001/XMLSchema-instance]"              xsi:schemaLocation="[https://jakarta.ee/xml/ns/persistence]              [https://jakarta.ee/xml/ns/persistence/persistence_3_1.xsd]">   <persistence-unit name= "jlogiPU" >     <jta-data-source> java:jboss/datasources/jlogiDS </jta-data-source>     <!-- list of JPA classes,  these aren't strictly required              since modern hibernate auto-discovers based on @Entity annotations     -->     <!-- properties for configurating this persistence unit -->     <properties>       <property name= "hibernate.hbm2ddl.auto" value= "update" />       <property name= "jakarta.persistence.schema-generation.create-source" value= "metadata" />       <property name= "jakarta.persistence.schema-generation.drop-source" value= "metadata" />       <!-- USE THIS ONLY FOR DEBUGGING!-->       <property name= "hibernate.show_sql" value= "false" />       <!--<property name= "hibernate.transaction.jta.platform" value= "org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform" /> -->       <!-- according to the wildfly startup the following prop is no longer required, commenting out for now--> <!--      <property name= "hibernate.dialect" value= "org.hibernate.dialect.PostgreSQLDialect" /> -->       <property name= "hibernate.jdbc.batch_size" value= "800" />     </properties>   </persistence-unit> </persistence>
