[JBoss JIRA] Created: (EJBTHREE-748) The implementation of equals() in org.jboss.ejb3.ProxyUtils.handleCallLocally() throws a NPE when being passed a null argument.
by Nicolas Bielza (JIRA)
The implementation of equals() in org.jboss.ejb3.ProxyUtils.handleCallLocally() throws a NPE when being passed a null argument.
-------------------------------------------------------------------------------------------------------------------------------
Key: EJBTHREE-748
URL: http://jira.jboss.com/jira/browse/EJBTHREE-748
Project: EJB 3.0
Issue Type: Bug
Environment: Embedded EJB3 container
Reporter: Nicolas Bielza
When looking up an entity bean, we get a proxy which implements equals() in a broken way:
Here's an example:
// Proxy NPE test:
InitialContext ctx = new InitialContext();
Manager m = (Manager)ctx.lookup("ManagerAction/local");
try {
if(m != null) {
m.equals(null);
}
System.err.println("What bug ???");
} catch(NullPointerException e) {
System.err.println("ProxyUtils NPE bug detected.");
e.printStackTrace();
}
And the output:
ProxyUtils NPE bug detected.
java.lang.NullPointerException
at org.jboss.ejb3.ProxyUtils.handleCallLocally(ProxyUtils.java:156)
at org.jboss.ejb3.ProxyUtils.handleCallLocally(ProxyUtils.java:137)
at org.jboss.ejb3.stateful.StatefulLocalProxy.invoke(StatefulLocalProxy.java:92)
at $Proxy34.equals(Unknown Source)
at com.alligacom.nett.NetTransferAdminInterface.<init>(NetTransferAdminInterface.java:49)
at com.alligacom.nett.NetTransferAdminInterface.main(NetTransferAdminI nterface.java:87)
The incriminated line (156) in ProxyUtils is:
return new Boolean(ih.toString().equals(args[0].toString()));
and should be:
return new Boolean(args[0] == null ? false : ih.toString().equals(args[0].toString()));

[JBoss JIRA] Created: (JBAS-4228) Preferred server HASingletonElectionPolicy
by Brian Stansberry (JIRA)
Preferred server HASingletonElectionPolicy
------------------------------------------
Key: JBAS-4228
URL: http://jira.jboss.com/jira/browse/JBAS-4228
Project: JBoss Application Server
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: Clustering
Reporter: Brian Stansberry
Assigned To: Brian Stansberry
An HASingletonElectionPolicy impl that allows configurable specification of a "preferred server". If the preferred server is running, it's the master, otherwise the master is deterministically selected based on the standard policy.
1) Determine if you are the preferred server by comparing you node name to the configured "preferred server" value.
2) When you get a view change, check if preferred server is in the view. If yes, and you're the preferred server, become master, otherwise don't. If preferred server is not in view, fall back on the base policy.
Have to make sure the mechanism of identifying and matching the "preferred server" is bullet proof (machine names vs. configuration-specified names vs. IP addresses, plus ports.)
