I'm not able to use custom UserType in when statement in 3.6.0+. The following exception is always thrown.

Exception in thread "main" java.lang.IllegalArgumentException: Unsupported constant Approved

It works fine with 3.5.1.

sample query:

QRequest r = QRequest.request;
JPAQuery q = new JPAQuery(em);
q.orderBy(r.status.when(new Approved()).then(0).otherwise(1).asc());

status field is defined as:

@Type(type = "com.xyz.status.StatusType")
private RequestStatus status;

StatusType is custom UserType which stores java object to database as string

public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session) throws HibernateException, SQLException {
        if (value == null) {
            st.setNull(index, StringType.INSTANCE.sqlType());
        } else {
            st.setString(index, value.getClass().getSimpleName());
