1. some JPA positional parameters have same position(?1)
2. the condition columns' java type is the same and the parameter value is the same
3. but the columns have different custom types
   Then parameter mapping works wrong.

example Entity mapping

@Type(type = "true_false")
@Column(name = "employee", columnDefinition = "char(1)")
 private Boolean employee;

@Type(type = "yes_no")
@Column(name = "male", columnDefinition = "char(1)")
private Boolean male;

@Column(name = "old")
private Boolean old;

example HQL query

final Query query = session.createQuery("from User user where employee = ?1 and male = ?1 and old = ?2");
query.setParameter("1", Boolean.TRUE);
query.setParameter("2", Boolean.FALSE);

Real query parameter mapping

1. 'T'
2. 'T' -> This must be 'Y' because second parameter custom type is 'yes_no'
3. FALSE

I made a sample project to reproduce this bug.
