Description:

Starting with Jboss 4.0.4 GA I get "Wrong Target" exception on any remote bean invokation after a redeploy. Only thing that helps is restaring JBoss.

How to repeat the bug:
-installing JBoss
*install a fresh JBOSS via http://jboss.sourceforge.net/jnlp/jems-installer-1.2.0.BETA3.jnlp
*choose: ejb3-clustered
*rest of installation process, provided defaults were used
*in $JBOSS_HOME/server/default/conf/standardjboss.xml: disable ipv6 support with an option for JVM:
-Djava.net.preferIPv4Stack=true
reason: IP6 does not work on ubuntu linux (see: http://wiki.jboss.org/wiki/Wiki.jsp?page=IPv6)

-building an example application
*example uses JBoss' internal database
*I used the Oreilly Workbook for Enterpreise Beans3.0 http://prdownloads.sourceforge.net/jboss/oreilly-ejb3-workbook_for_jboss404_GA.zip?download
*unzip workbook to $WORKBOOK
*change to directory $WORKBOOK/ex04_1
*set JAVA_HOME, and JBOSS_HOME to required pathes
*build and deploy example with: ant
*run client with: ant run.client
=>everything is working
*touch the deployed jar with: touch $JBOSS_HOME/server/default/deploy/titan.jar
*application is redeployed
*run client with: ant run.client
=>the following error message is shown:
