[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-999) Bridge startup should retry if remote destinations are not available

[Howard Gao (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBMESSAGING-999?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12442150#action_12442150 ] 

Howard Gao commented on JBMESSAGING-999:
----------------------------------------

Proposed Fix:

1. In BridgeService we only do properties validation.
2. In Bridge, we add a BridgeState object, which has BRIDGE_STARTUP, BRIDGE_OK, BRIDGE_FACT_FAILURE, BRIDGE_DEST_FAILURE, BRIDGE_STOP.

3. In Bridge.start()

3.0 Set bridge state to BRIDGE_STARTUP;
3.1 Start a validating thread.
3.3 start working thread.
3.3 both threads will watch on a BridgeState object

if state is BRIDGE_STARTUP, the validating thread starts to work, checking factories connections, destinations etc. If everything ok, set state to BRIDGE_OK. Then waiting.

if state is BRIDEG_OK, the working thread works. it will do normal work as is implemented so far. During work, any failure will set the state to a failure state and will then block the working thread and make the validating thread wake up and work.

The validating thread will check and retry things based on the specific state. If failed, set the state to BRIDGE_STOP, thus making the service stop. If retry OK, then let the working thread continue the bridging job.

> If remote provider is not available at startup it will fail to start.
> We should change this by institutiing a retry at startup too.
