[jboss-jira] [JBoss JIRA] (DROOLS-474) java.lang.IllegalStateException: There's already another KieContainer created from a different ClassLoader

[Mario Fusco (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-474?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mario Fusco resolved DROOLS-474.
--------------------------------

    Resolution: Rejected


I agreed with Charles that is not a bug in drools, but the problem was caused by the duplicated pom.properties file.

He correctly suggested that we could give a more understandable error message but at the moment I don't see how we could discover that the problem depends on the duplicated pom file there. The same exception could be actually caused by other similar misconfiguration, so just catching the exception and telling the user in a log message that he has a duplicated pom could be misleading.
