Description of problem:
Unexpected exception. Returned exception indicates that query failed but there is no reason in message.

How reproducible:
Source databse - Ingres
VDB view model - BQT2
  tables: smallb - 
  `INTKEY` integer primary key,
  `STRINGKEY` varchar(10),
  `INTNUM` integer,
  `STRINGNUM` varchar(10),
  `FLOATNUM` real,
  `LONGNUM` bigint,
  `DOUBLENUM` double,
  `BYTENUM` tinyint,
  `DATEVALUE` date,
  `TIMEVALUE` time,
  `TIMESTAMPVALUE` timestamp,
  `BOOLEANVALUE` boolean,
  `CHARVALUE` character(1),
  `SHORTVALUE` smallint,
  `BIGINTEGERVALUE` bigint,
  `BIGDECIMALVALUE` decimal(10,0),
  `OBJECTVALUE` byte

SQL query - SELECT intkey FROM BQT1.SmallA AS A WHERE stringkey = (SELECT stringkey FROM BQT1.SmallA AS B WHERE b.intnum = a.intnum ) ORDER BY intkey

Actual results:
TEIID30504 Remote org.teiid.core.TeiidProcessingException: TEIID30504 Source: 4502 TEIID11008:TEIID11004 Error executing statement(s): [Prepared Values: [] SQL: SELECT g_0.intkey AS c_0 FROM smalla AS g_0 WHERE g_0.stringkey = (SELECT g_1.stringkey FROM smalla AS g_1 WHERE g_1.intnum = g_0.intnum) ORDER BY c_0]
