Hi,
currently if a tx will be rollbacked, the SpringTransaction class kind of
swallow the root cause in the following code
catch (TransactionSystemException e)
| {
| log.error("Exception cause:", e);
| throw new SystemException(e.getMessage());
| }
| catch (UnexpectedRollbackException e)
| {
| log.error("Exception cause:", e);
| throw new RollbackException(e.getMessage());
| }
It is essential to pass the whole cause exception in SystemException and
RollbackException instead of only a text message.
My use case is the following:
JSF delete action method tries to delete a row in the db. When the tx commits,
it discovers the row can not be deleted because of foreign key constraint. I
would like to have the ConstraintViolationException wrapped in the
RollbackException, so that I have a chance to handle this exception later with
the exception handler.
In the current implmenetation, the RollbacklException with only text message
and no cause stack will later be wrapped as an IllegalStateException, which is
not helpful for exception handling at all.
