Weblogic.utils.AssertionError when getting attributes of EJBComponentMBean

Question

when i get the attributes of this mbean, i get an assertion error. the
javadocs do not say anything about this...so how can i prevent this
assertion error?
here is the code, and below is the error on weblogic
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, "t3://yscadt207:7001");
p.put(Context.SECURITY_PRINCIPAL, "weblogic");
p.put(Context.SECURITY_CREDENTIALS, "weblogic");
Context ctx = null;
try {
ctx = new InitialContext(p);
MBeanHome home = (MBeanHome)ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
MBeanServer server = home.getMBeanServer();
Set set = server.queryNames(new
ObjectName("*:Type=EJBComponent,*"), null);
System.out.println("found " + set.size() + " mbeans");
int show = 1;
int count = 0;
for(Iterator i = set.iterator(); show > count && i.hasNext();
count++){
ObjectName on = (ObjectName)i.next();
System.out.println(on);
MBeanInfo info = server.getMBeanInfo(on);
MBeanAttributeInfo[] attinfo = info.getAttributes();
for(int j = 0; j < attinfo.length; j++){
try {
System.out.println(attinfo[j].getName() + " (" +
attinfo[j].getType() +
"): " +
server.getAttribute(on,
attinfo[j].getName()));
} catch(Exception ex){
System.err.println("error for att " + attinfo[j].getName()
+ " (" + attinfo[j].getType() + "): " + ex);
ex.printStackTrace();
} finally {
if(ctx != null) ctx.close();

I am also getting the exact same errors.
In my case it's when I have MC4J connected to WLS8.1SP3 and I am trying to simply look at the deployed EJB's.
Why has no one answered Simon's question since being posted back in Feb?
