[teiid-issues] [JBoss JIRA] (TEIID-1899) Getting Assertion when running Inner Merge Join query with SELECT COUNT(*) on top

[Van Halbert (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-1899?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12660240#comment-12660240 ] 

Van Halbert commented on TEIID-1899:
------------------------------------

Also seeing it with this query:

SELECT ORDERS.O_ORDERKEY, ORDERS.O_ORDERDATE, ORDERS.O_CLERK, CUSTOMER.C_CUSTKEY, CUSTOMER.C_NAME, CUSTOMER.C_ACCTBAL 
FROM TPCR01_PostgreSQLVirt.ORDERS, TPCR01_OracleVirt.CUSTOMER WHERE (CUSTOMER.C_CUSTKEY = ORDERS.O_CUSTKEY) AND 
(ORDERS.O_ORDERDATE < '1992-01-05 00:00:00') AND (CUSTOMER.C_ACCTBAL > 9514.5)

Each table, with its where clause, works.  But combine the ASSERTION occurs:

10:58:11,842 ERROR [PROCESSOR] Unexpected exception for request LV4pMCDmToOE.11
java.lang.AssertionError: ASSERTION FAILED: expected reference to be not null
