Paul Richardson commented on JBTIS-260:
---------------------------------------

Updated Designer 8.3.x to a target platform of Integration-stack version 4.1.8.Final. This now matches JBDS 7.1.1 org,eclipse.datatools.connectivity plugins. However, this does not fix the problems.

Consistently trying to execute a vdb results in a three exceptions, one of which has the following stacktrace:
{code}
java.lang.NullPointerException
	at org.eclipse.datatools.connectivity.drivers.DriverValidator.validateJarListFiles(DriverValidator.java:161)
	at org.eclipse.datatools.connectivity.drivers.DriverValidator.isValid(DriverValidator.java:92)
	at org.eclipse.datatools.connectivity.drivers.jdbc.JDBCConnection.getDriverDefinitionJarPaths(JDBCConnection.java:217)
	at org.eclipse.datatools.connectivity.drivers.jdbc.JDBCConnection.getJdbcDriverJars(JDBCConnection.java:169)
	at org.eclipse.datatools.connectivity.drivers.jdbc.JDBCConnection.<init>(JDBCConnection.java:67)
	at org.teiid.datatools.connectivity.TeiidJDBCConnection.<init>(TeiidJDBCConnection.java:31)
	at org.teiid.datatools.connectivity.TeiidJDBCConnectionFactory.createConnection(TeiidJDBCConnectionFactory.java:21)
	at org.eclipse.datatools.connectivity.internal.ConnectionFactoryProvider.createConnection(ConnectionFactoryProvider.java:83)
	at org.eclipse.datatools.connectivity.internal.ConnectionProfile.createConnection(ConnectionProfile.java:359)
	at org.eclipse.datatools.connectivity.internal.ManagedConnection.createConnection(ManagedConnection.java:166)
	at org.eclipse.datatools.connectivity.internal.CreateConnectionJob.run(CreateConnectionJob.java:56)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)
{code}

Looking at the source of this exception leads to the DriverValidator and this line:
{code}
boolean emptyJarListIsOK = this.mTemplate.getEmptyJarListIsOKFlag();
{code}

Clearly, mTemplate being null is generating the NullPointerException. This field is directly extracted from the DriverInstance (Teiid driver instance) upon construction of the validator so the teiid driver must have a null template. *Why??*

By opening the connection properties of the vdb's connection, the driver properties section is blank with no actual JDBC driver selected. By choosing the 8.4.x driver from the dropdown list, the teiid connection starts to work again and a query can be successfully made. So, *why is the appropriate driver for the teiid version not selected??*
