Build Identifier: eclipselink-2.3.0.v20110604-r9504

Using entity:

@Entity
@Table(name="EMPLOYEE")
public class Employee implements java.io.Serializable {

    private int                  id;
    private String         firstName;
    private String         lastName;
    private float                 salary;


    public Employee() {
    }

    public Employee(int id, String firstName, String lastName, float salary)
    {
            this.id = id;
            this.firstName = firstName;
            this.lastName = lastName;
        this.salary = salary;
    }

   // ===========================================================
   // getters and setters for the state fields

    @Id
    @Column(name="ID")
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }

    @Column(name="FIRSTNAME")
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    @Column(name="LASTNAME")
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    @Column(name="SALARY")
    public float getSalary() {
        return salary;
    }
    public void setSalary(float salary) {
        this.salary = salary;
    }

------------------
client code:

        try {
            Query q = getEntityManager().createQuery(
                    "UPDATE Employee e SET e.salary = e.salary * 10.0");
            q.setLockMode(LockModeType.PESSIMISTIC_READ);
            System.out.println("IllegalStateException should have been thrown");
        } catch (IllegalStateException e) {
            System.out.println("Got TransactionRequiredException as expected");
        } catch (Exception e) {
            System.out.println("Unexpected exception occurred", e);
        }

------------------
output:

Unexpected exception occurred
java.lang.IllegalArgumentException: A lock type can only be used with a select query (which allows the database to be locked where necessary).
