We should avoid using exceptions for flow control when acquiring
state transfer lock
------------------------------------------------------------------------------------
Key: ISPN-1799
URL:
https://issues.jboss.org/browse/ISPN-1799
Project: Infinispan
Issue Type: Task
Components: State transfer
Affects Versions: 5.1.0.FINAL
Reporter: Dan Berindei
Assignee: Dan Berindei
Fix For: 5.1.4.FINAL
We currently use `StateTransferInProgressException` as a marker that a write command
failed to acquire the state transfer lock and it should be retried. With ISPN-1704 I added
another exception, StateTransferLockReacquisitionException, to signal that a write command
failed to re-acquire the state transfer lock after it had already acquired it.
These exceptions often appear in the logs and confuse users (see ISPN-1610), so it would
be best to use special return values. We may also need a flag in the InvocationContext for
StateTransferLockReacquisitionException.
