URL: https://github.com/apache/incubator-kie-issues/issues/2070
When running a Spring Boot app that uses JPA user-task storage by adding the
jbpm-addons-springboot-usertask-storage-jpa dependency , two problems occur:
On user task activation, Hibernate can’t find the JPA entity classes from
the addon. -> UnknownEntityTypeException.
```
java.lang.IllegalArgumentException: Unable to locate persister:
org.jbpm.usertask.jpa.model.UserTaskInstanceEntity
at org.hibernate.internal.SessionImpl.firePersist(SessionImpl.java:764)

```
On timer/abort paths, user-task persistence code runs outside a transaction,
causing TransactionRequiredException and LazyInitializationException when
loading lazy collections.
```
