I may give you alternative solution, I use it for different situations, but
currently I write it "by hand". It's JPA aware, not bound to hibernate. Try
this:
public class entity {
    private int intAsBool;
    private boolean boolValue;

    @Column()
    protected int getIntAsBool() {...}
    protected void setIntAsBool(int val) {...}

    @Transient
    public boolean getBoolValue() {...}
    public boolean setBoolValue() {...}

    @PostLoad
    protected void postLoad() {
        setBoolValue(getIntAsBool() == 1);
    }

    @PrePersist
    @PreUpdate
    protected void preStore() {
        setIntAsBool(getBoolValue() ? 1 : 0);
    }
}

Bear in mind you need to choose only one way to mark JPA annotations field or
ancestors, 2nd one is better for many reasons.

Hope this help. I use this construct to store and map T/N char(1) values to
boolean.
