Summary0033137: Useless m_product read from services product even if services are not used
DescriptionThe addition of services project with createLinesForServiceProduct and the HashMap orderlineServiceList added a m_product read to OrderLoader which is not required if services are not used.

That extra overhead should be at least avoided if services are not used.

Relevant code is in createOrderLines:
      if ("S".equals(orderline.getProduct().getProductType())) {
        // related can be null
        if (jsonOrderLine.has("relatedLines")) {
          orderLineServiceList.put(orderline.getId(), jsonOrderLine.getJSONArray("relatedLines"));

The conditions can be swapped around to avoid the getProduct() call if there is no relatedLines in the json.
Steps To ReproduceTrace all SQL of orderloader.

Patch in 2 parts:
a.) Review createLinesForServiceProduct function which only does any real work if the 'value' part of the HashMap is not null.
So the else part inside createOrderLines which insert into the HashMap with value=null is useless.
33137_part1.diff cleans up that part to avoid some overhead and simplify the code.

b.) Now with the part inside createOrderLines simplified the 2 if conditions can be swapped around which does not trigger getProduct() sql read unless there is really a relatedLines item present in the json.

So the read overhead is removed unless services/relatedLines are really used.

Issue 33137. Simplify code related to createLinesForServiceProduct.

The only reader of the HashMap orderLineServiceList only does any processing
if the value part of the map is not null.
So avoid inserting into the HashMap any entries which have value null as those
are not useful (and remove the != null check also)

Fixed 33137. Avoid m_product read if not service lines are used.

Swap check condition for m_product.getType() == S and if the json
has a relatedLines part.
By checking json first we avoid the m_product read in the normal case.
