thank you for your help. Adapter is almost ready, but there is still one 
test case: org.apache.cayenne.access.NestedDataContext_DeadlockTest, 
which fails. Test passes only if checking threads is delayed few second 
- probably firebird performance is to low.

Test org.apache.cayenne.query.SelectQueryTest#testSelectLongIn(), ends 
with error because of generated statement size and firebird limitations 
( Are such errors aceptable?

Some tests, which tries to delete all records from table where one 
record has reference to other record in _the same table_ also ends in 
error. Usually in method setUpAfterInjection(), which prepares database 
to test.
Firebird doesn't recognise that all records are deleted and denies 
breaking foreign key constraint.
Example of such case is org.apache.cayenne.access.JoinPrefetchTest.

My question is how to deal with such errors? In this case solution might 
be removing references before clearing table, but I'm not sure it is 
good idea to change code of test cases.
