Scheduler throws NPE for suspended requests with non-distributed virtual
databases
----------------------------------------------------------------------------------
Key: SEQUOIA-848
URL: https://forge.continuent.org/jira/browse/SEQUOIA-848
Project: Sequoia
Type: Bug
Components: Core
Versions: Sequoia 3.0 beta1, Sequoia 2.10.2
Reporter: Emmanuel Cecchet
Assigned to: Emmanuel Cecchet
Priority: Blocker
Fix For: Sequoia 2.10.3, Sequoia 3.0
As reported on the Sequoia mailing list by Xavier Roques:
The code of the method AbstractScheduler.addSuspendedRequest is
synchronized (suspendedRequests)
{
suspendedRequests.add(obj);
}
synchronized (totalOrderQueue)
{
totalOrderQueue.notifyAll();
}
But if the VirtualDatabase is not a DistributedVirtualDatabase,
the field totalOrderQueue queue is null and a NPE is thrown.
