Major Description
I tried to simulate failover with Teiid. I have two SOA-P (ER7 build) nodes. When I killed first node, client correctly switched to second node. Then I re-started first node and killed second node. Client failed with the exception and did not switch back to first node.
Client was very simple - querying VDB in infinite loop and printing result to stdout.
What I did was:
1) I started both nodes, the started a client
2) Killed node no.1 with 'CTRL+Z' and 'kill -9 %1'
3) Client switched to node2
4) Re-started node no.1
5)Killed node no2 with 'CTRL+Z' and 'kill -9 %1'
6)Client failed with exception:
1 [InvalidSessionException]The specified session ID "null" is invalid. It cannot be found in the userbase.
