Fix deadlock in ConnectionValidator
-----------------------------------
Key: JBREM-1070
URL: https://jira.jboss.org/jira/browse/JBREM-1070
Project: JBoss Remoting
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 2.2.2.SP10, 2.5.0.SP2 (Flounder)
Reporter: Ron Sigal
Assignee: Ron Sigal
Fix For: 2.2.2.SP11, 2.5.0.SP3 (Flounder)
org.jboss.remoting.ConnectionValidator.run() synchronizes on the "lock" variable, which is needed by notifyListeners() in the event of a network failure. In general, the calls in run() to either doCheckConnectionWithLease() or doCheckConnectionWithoutLease() should time out so that run() gives up the "lock" variable, but, if run() executes again soon enough, it can grab "lock" again before notifyListeners() can run.

[JBoss JIRA] Created: (JBREM-1069) Make ConnectorValidator configure ping period correctly

Make ConnectorValidator configure ping period correctly
-------------------------------------------------------
Key: JBREM-1069
URL: https://jira.jboss.org/jira/browse/JBREM-1069
Project: JBoss Remoting
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 2.2.2.SP10, 2.5.0.SP2 (Flounder)
Reporter: Ron Sigal
Assignee: Ron Sigal
Fix For: 2.2.2.SP11, 2.5.0.SP3 (Flounder)
When the overloaded org.jboss.remoting.Client method
public void addConnectionListener(ConnectionListener listener)
is called, it puts the default value org.jboss.remoting.ConnectionValidator.DEFAULT_PING_PERIOD (actual value 2000) in the metadata map passed to ConnectionValidator. Since the metadata map overrides the Client's configuration map, the value in the Client's configuration map, which can come from the InvokerLocator or Connector configuration, is ignored.
In particular, the JBossMessaging class org.jboss.jms.client.remoting.JMSRemotingConnection calls that version of Client.addListener().
