ClasscastException: Cannot Cast org.jboss.ha.framework.server.HAPartitionImpl cannot be cast to org.jboss.ha.framework.server.HAPartitionImpl
by Dharmveer Jain
Hi,
I have setup a cluster partition in Jboss and trying to retrieve HAPartition
object from ClusterPartition mbean. Below is my code:
ArrayList<MBeanServer> list = MBeanServerFactory.findMBeanServer(null);
for (MBeanServer server : list)
{
String onStr = "jboss:service=DefaultPartition";
ObjectName objectName = new ObjectName(onStr);
Set mbeans = server.queryMBeans(objectName, null);
Object partitionObj = server.invoke(theName, "getHAPartition",
null, null);
org.jboss.ha.framework.server.HAPartitionImpl partition =
(org.jboss.ha.framework.server.HAPartitionImpl) partitionObj; //this line
throwing ClassCastException
}
The last line in above code is throwing ClasscastException: Cannot Cast
org.jboss.ha.framework.server.HAPartitionImpl cannot be cast to
org.jboss.ha.framework.server.HAPartitionImpl
I have same version of jbossha.jar in jboss lib and war's web-inf/lib
folder. I am not sure why it is throwing classcast exception. Any help is
much appreciated.
Thanks in advance !!!
Regards,
Dharmveer

The lib directory contains jars with full name; e.g.
jboss-classloading-vfs-2.0.7.CR2.
Is this part of mvn refactoring or is it just me?

Re: [jboss-dev] [jboss-cvs] JBossAS SVN: r94875 - in projects/jboss-cl/trunk: classloader/src/main/java/org/jboss/classloader/spi/filter and 7 other directories.
by Adrian Brock
You're probably right, although I don't trust volatile.
It's my c and pre Java5 background. ;-)
The issue flagged by FindBugs was that some access to
this ivar was synchronized and some wasn't.
The gets and sets were synchronized.
The real issue was code like the following
in an unsynchronized method:
if (loadedClass != null)
doStuff();
blah();
if (loadClass == null)
doSomethingElse();
Which won't work with volatile. The two if statements could
potentially see different values (although in practice
they won't in this use case).
However, I also fixed that code to copy the ivar into a local variable
at the start of the method so it has a consistent view
throughout, which should mean volatile is ok. At least with
the lastest java memory model. ;-)

Re: [jboss-dev] Tag for JBoss CL
by Adrian Brock
Nice timing. ;-)
I'll release it as it is now.
There's nothing major in the FindBugs report.
The only thing I've committed so far is to make ClassFilter Serializable
which obviously creates no problems.

Re: [jboss-dev] [JBoss JIRA] Updated: (JBCL-123) Fix problems flagged by FINDBUGS
by Adrian Brock
I've just bumped it to the next release.
I'm not doing the FindBugs stuff for 2.0.7.GA since its wanted
today and we won't have to time to make sure there are
no regressions caused.
If we do a CRx release for 2.0.8 then its just a question
of renaming 2.0.8.GA to 2.0.8.CR1 in JIRA.

AS6 Boot time & Deployment time container task
by Jason T. Greene
I have created a container jira task with all of the items we identified
during the past AS6 meeting:
https://jira.jboss.org/jira/browse/JBAS-7329
Since each of these tasks is rather large, feel free to link any of them
to a larger container task.
Also, please add to it if you happen to work on something else that is
related to deployment or boot time.
Thanks!
