EqlParser prohibits the use of reserved words (JPQL aggregate functions) in entity field names #3829
Description
Attached you will find a reproducer that implements a sample application with JPA Entity "Item" containing field "size" and corresponding repository ItemRepository. The repository contains only one method with query select sum(i.size) from Item i.
Running this app leads to error org.springframework.data.jpa.repository.query.BadJpqlGrammarException: At 1:13 and token 'size', no viable alternative at input 'select sum(i.*size) from Item i'; Bad EQL grammar [select sum(i.size) from Item i].
If the field 'size' is renamed to 'sizeInBytes' the app is running with no errors.
If a query parser is switched to HqlParser the app is running fine as well.
