When running BQT tests, an Assertion error is seen when batches are being processed ----------------------------------------------------------------------------------- Key: TEIID-1076 URL: https://jira.jboss.org/jira/browse/TEIID-1076 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.0 Reporter: Van Halbert Assignee: Van Halbert Fix For: 7.0 I am testing BQT pushdown on MS3 and seeing several "java.lang.AssertionError" occurring on all sources. This is one example of a query and the exception. Any idea what is going on?
