      Description

      If i use constants like this :

      SELECT object FROM MyObject object WHERE object.path LIKE '%|_%' ESCAPE '|'

      all is ok, but if I want to use parameters - exception is thrown.

      Example:

      @Entity
      @Table(name="simple_object")
      public class MySimpleObject {

      @Id
      String Id ;

      @Basic
      @Column(name="value", nullable=false, length=36)
      String value ;
      .....................
      .......................

      EntityManager em = emf.createEntityManager() ;
      Query q = em.createQuery("SELECT x FROM MySimpleObject x WHERE x.value LIKE ?1 ESCAPE '|'") ;
      q.setParameter(1, "%|_%") ;
      List<MySimpleObject> res = q.getResultList() ;

      Exception in thread "main" <openjpa-1.1.0-SNAPSHOT-r422266:648359 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: Encountered "ESCAPE" at character 54, but expected: ["AND", "GROUP", "HAVING", "OR", "ORDER", <EOF>].
