cannot init cause of ClassCastException
---------------------------------------
Key: JBREM-552
URL: http://jira.jboss.com/jira/browse/JBREM-552
Project: JBoss Remoting
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 2.0.0.Beta2 (Boon)
Reporter: John Mazzitelli
Assigned To: Tom Elrod
Priority: Minor
Fix For: 2.0.0.CR1 (Boon)
I'm in a catch clause within InvokerRegistry and I'm getting a weird exception
thrown:
java.lang.IllegalStateException: Can't overwrite cause
at java.lang.Throwable.initCause(Throwable.java:320)
at org.jboss.remoting.InvokerRegistry.loadClientInvoker(InvokerRegistry.java:447)
at org.jboss.remoting.InvokerRegistry.createClientInvoker(InvokerRegistry.java:324)
at org.jboss.remoting.Client.connect(Client.java:385)
at

at
org.jboss.on.communications.command.client.ServerPollingThread.run(ServerPollingThread.java:102)
Look at line 447 and you'll see it is trying to init the cause of a
ClassNotFoundException. Running in a debugger, the newly constructed exception created on
446 has a null cause. Looking then at Throwable.initCause and you'll see a null cause
causes this IllegalStateException to be thrown. The cause needs to be "this",
not null (I don't know why, seems like it should also look for null, but whatever -
that's the way the JDK is written).
The fix is simple - use the constructor that takes a throwable as its second parameter.
Not sure why initCause it being used, as opposed to this constructor.
e.g.:
new ClassNotFoundException("Can not invoke loadClientInvokerClass method on " +
transportFactoryClass, e);
(notice the ", e" parameter).
There are three other instances where initCause is called on ClassNotFoundException that
also need to be fixed. See the other catch clauses in here.

---------------------------------------
The way this is now, its also bad because you lose all the cause stack traces as well. So
the context of where the problem actually occurred is lost.
Changing this to use the proper constructor should fix this

[ http://jira.jboss.com/jira/browse/JBREM-552?page=all ]
Tom Elrod resolved JBREM-552.
------------------------------
Resolution: Done
Will now just throw the root exception (instead of trying to wrap with a ClassNotFound
one).
