one hibernate select generating a lot of sql statements

I am running a following statement in hibernate:
somelist = session.find("from Rfq rfq order by rfq.po.poDate asc where rfq.po.buyerCode='GAK'");

Instead of generating one line for this select I am getting a few dozen of lines of sql from hibernate:

The first one makes sense:

Hibernate: select rfq0_.RFQ_ID as RFQ_ID, rfq0_.ISSUED_BY as ISSUED_BY, rfq0_.RELEASE_DATE as RELEASE_3_, rfq0_.BID_CLOSE_DATE as BID_CLOS4_, rfq0_.TAX_INFORMATION as TAX_INFO5_, rfq0_.FOB as FOB, rfq0_.SPECIAL_INSTRUCTIONS as SPECIAL_7_, rfq0_.RFQ_CONSTANT as RFQ_CONS8_, rfq0_.RFQ_BUYER_CODE as RFQ_BUYE9_, rfq0_.RFQ_BLUES_CODE as RFQ_BLU10_, rfq0_.RFQ_SEQ_REVISION_NUMBER as RFQ_SEQ11_, rfq0_.RFQ_STATUS as RFQ_STATUS, rfq0_.PO_ID as PO_ID, rfq0_.INCREMENTAL_PRICE_QUOTE as INCREME14_ from RFQ_TABLE rfq0_, PO_LIST po1_ where rfq0_.PO_ID=po1_.PO_ID and po1_.SOURCE != 'WEBPO - IDS' AND po1_.active = 1 and ((po1_.BUYER_CODE='GAK'  and rfq0_.PO_ID=po1_.PO_ID)) order by  po1_.PO_DATE asc

And then a few dozen times of:

Hibernate: select po0_.PO_ID as PO_ID0_, po0_.PARENT_PO_ID as PARENT_P2_0_, po0_.PO_NUMBER as PO_NUMBER0_, po0_.CHANGE_ORDER_SEQ as CHANGE_O4_0_, po0_.SOURCE as SOURCE0_, po0_.PO_DATE as PO_DATE0_, po0_.LOAD_DATE as LOAD_DATE0_, po0_.FILENAME as FILENAME0_, po0_.LOAD_INFO as LOAD_INFO0_, po0_.CREATOR as CREATOR0_, po0_.SUPPLIER_NAME as SUPPLIE11_0_, po0_.SUPPLIER_NUMBER as SUPPLIE12_0_, po0_.BUYER_CODE as BUYER_CODE0_, po0_.BUYER_DEPT as BUYER_DEPT0_, po0_.CONTRACT as CONTRACT0_, po0_.ACTIVE as ACTIVE0_, po0_.PO_TYPE_ID as PO_TYPE_ID0_ from PO_LIST po0_ where po0_.PO_ID=?

Here are the relevant mapping files:
