      Description

      When I try to get an object from my database via entity manager that includes a further object that is annotated with @OneToMany and the parameter "fetch = FetchType.EAGER", I got the following exception (below are more Information about my entities and testcases):

      ________________________________________________

      I created 2 new entities for my tests, they look like this:

      @Entity
      @Table(name = "parent")
      public class Parent {

      @Id
      @GeneratedValue(strategy = GenerationType.TABLE, generator = "parentGen")
      @TableGenerator(name = "parentGen", table = "jpa_sequence", pkColumnName = "ID",
      pkColumnValue = "parent", valueColumnName = "SEQUENCE_VALUE", allocationSize = 1)
      public long oid;

      @OneToMany(mappedBy = "parent", fetch = FetchType.EAGER)
      private List<Child> children;

      public long getOid() {
      return oid;
      }

      public void setOid(long oid) {
      this.oid = oid;
      }

      public List<Child> getChildren() {
      return children;
      }

      public void setChildren(List<Child> children) {
      this.children = children;
      }
      _______________________________________

      @Entity
      @Table(name = "child")
      public class Child {

      @Id
      @GeneratedValue(strategy = GenerationType.TABLE, generator = "childGen")
      @TableGenerator(name = "childGen", table = "jpa_sequence", pkColumnName = "ID",
      pkColumnValue = "child", valueColumnName = "SEQUENCE_VALUE")
      public long oid;

      @ManyToOne
      private Parent parent;

      public long getOid() {
      return oid;
      }

      public void setOid(long oid) {
      this.oid = oid;
      }

      public Parent getParent() {
      return parent;
      }

      public void setParent(Parent parent) {
      this.parent = parent;
      }
      ____________________________________

      Further information:

      My jpql: select p from Parent p
      If I change the FetchType to "LAZY" (or leave it just out) I got my result normaly and the children object (the list) is null of course, but if I call the getter of the list now (in the transaction), the object will be filled normaly without this exception.
      Furthermore this exception does not occur when I have just 1 parent with child objects. I can have several parents and children in my tables, but when more than 1 parent have children referenced in the database, this exception will be thrown.
      Also if I change the type of "oid" from "long" to "int" the exception will change, too: "...LongId cannot be cast... -> ...IntId cannot be cast..."
      I used: Java 8 with jpa 2.1.0 and 2.2.2, Java 6 with jpa 2.2.2
      MySQL Database
      Apache Tomcat
