jboss-cli failed to remove PostgreSQL datasource module NullPointerException OperationContextImpl.doRemove()

NullPointerException during jboss-cli remove with command:

jboss-cli --connect command="/subsystem=datasources/jdbc-driver=bop:remove"

Console and log below.

This happens when standalone.xml has XML entry for driver that does not exist (see "Steps to Reproduce"). I have also seen this happen in a case where the driver does exist; not sure how the latter happened, or how important that is.

MS-DOS Console:
{
"outcome" => "failed",
"failure-description" => "JBAS014749: Operation handler failed: null",
"rolled-back" => true
}
