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.
