--------------------------------------

This stack trace appears as part of the issue:  3360.  Please compare your problem with the
description in DERBY-3360 to see if this is the same problem.  In DERBY-3360 the problem is
secondary to the real problem are you also seeing  this message  posted to your derby.log:

2008-01-29 10:44:58.987 GMT Thread[Main,5,main] Equally severe exception raised during cleanup
(ignored) null
java.lang.NullPointerException
 . . .

INFO from 3360:
Problem SQL:  SQL: SELECT A.a, D.b, B.c, C.d FROM C JOIN A ON C.e = 'I' AND A.f IS NOT NULL
AND A.g = C.g AND FN_MATCHES(A.f, C.d) <> 1 JOIN B ON B.h = A.g JOIN D ON D.h = URID.h


W/A: CAST(FN_MATCHES(..) AS INTEGER) avoids the bug.
