> Escape character in JPQL/SQL with parameter substitution generates incorrect SQL. E.g.
> "SELECT 'TRUE' AS VAL FROM DUAL WHERE '\\' = ?"
> or 
> "SELECT * FROM ( SELECT FOLDER_ID, SYS_CONNECT_BY_PATH(NAME,'\\') AS PATH FROM PROJECT_FOLDER
START WITH PARENT_ID IS NULL CONNECT BY PRIOR FOLDER_ID = PARENT_ID ) WHERE PATH LIKE ?"
> the '\\' will be transformed to '' and causes SQLException when send to the db server.
