我有以下问题：
这是我为给定的

public class SearchRepoImpl<T, ID extends Serializable>  implements SearchRepo<T,ID> {

    private final EntityManager em;

    @Override
    public Stream<T> findStreamBySpec(Specification<T> where, Integer limit, Class<T> clazz) {
        final Class<T> domainClass = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];

        CriteriaBuilder builder = em.getCriteriaBuilder();
        CriteriaQuery<T> query = builder.createQuery(domainClass);

        applySpecificationToCriteria(where, domainClass, query); // this method does the necessary preprocessing and is of no interest
        return em.createQuery(query)
                .getResultStream()
                .limit(limit.longValue());
    }
}

但是，当我使用searchRepo.findStreamBySpec(spec, 100, MyClass.class).forEach(e-> {...})调用此实现时，我会遇到以下异常：
org.hibernate.exception.GenericJDBCException:由于调用isBeforeFirst或isAfterLast（）时发生异常，无法确定结果集是否为空
我已经设法将这个问题追溯到DB2驱动程序中的一行反编译代码：

private final void checkThatResultSetTypeIsScrollable() throws SQLException {
   if (this.resultSetType_ == ResultSet.FORWARD_ONLY) {
      throw hd.a(this, this.agent_.logWriter_, ErrorKey.METHOD_NOT_ALLOWED_ON_FORWARD_ONLY_CURSOR, "10900");
   }
}

此方法又从HikariProxyResultSet调用

public boolean isBeforeFirst() throws SQLException {
        this.agent_.systemMonitor_.c();

        boolean var2;
        try {
            if (this.agent_.loggingEnabled()) {
                this.agent_.logWriter_.traceEntry(this, "isBeforeFirst");
            }

            this.checkForClosedResultSet();
            this.checkThatResultSetTypeIsScrollable();
          //^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ calls above method checkThatResultSetTypeIsScrollable()
            boolean var1 = this.isBeforeFirstX();
            if (this.agent_.loggingEnabled()) {
                this.agent_.logWriter_.traceExit(this, "isBeforeFirst", var1);
            }

            var2 = var1;
        } finally {
            this.agent_.systemMonitor_.a(this.statement_);
        }

        return var2;
    }

它是从

private boolean isResultSetEmpty() {
        try {
            return currentPosition == 0 && !getResultSet().isBeforeFirst() && 
!getResultSet().isAfterLast();
                                         //^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ calls above method  isBeforeFirst()           
        }
        catch (SQLException e) {
            throw getSession().getFactory().getSQLExceptionHelper().convert(
                    e,
                    "Could not determine if resultset is empty due to exception calling isBeforeFirst or isAfterLast()"
            );
        }
    }

我的问题是，是否有办法向Hibernate、HikariCP和/或DB2暗示或建议我不想将ResultSet设置为FORWARD_ONLY，或者我不想使用那种可滚动的结果。
