Fay Wang commented on OPENJPA-838:
----------------------------------
The problem of parameter setting when cache is on is a result of how OpenJPA
processes parameters. There is no distinction between literal vs.
user-specified parameters and there is no clear-cut way to separate parameter
setting logic from the logic to reconstruct SQLBuffer within SelectImpl, making
re-using SQLBuffer within SelectImpl impossible,
> fix parameter setting problem when QuerySQLCache is on
