Yes, and under normal conditions it does this (there are appropriate
checks there). But the NPE can happen there when either fixedStmt or
fixedStmt.getInSqlda() is null. There is only one place where fixedStmt
is assigned to null - in a close method of its superclass. But there are
appropriate checks in the AbstractPreparedStatement. So, this is
definitely combination of Hibernate and Jaybird, but I would be very
interested to find out how it was possible.
