[ http://issues.apache.org/jira/browse/XALANJ-1993?page=comments#action_57524 ] Ilene Seelemann commented on XALANJ-1993: -----------------------------------------
I haven't been able to reproduce this issue using IBM JDK 1.3.1. It looks as if the ListResourceBundles are being looked up and found correctly. The JDK first tries to load the class specified in the ResourceBundle.getResourceBundle method and then if that fails it looks for a .properties file with the same name. I could see you getting the ClassCastException if for some reason you don't have the ListResourceBundle files, but you do have .properties files lying around. Once upon a time I think we used .properties files instead of the classes. Or maybe I'm missing something. Can you describe your environment in more detail? Thanks. > proposed fix to ClassCastException in org.apache.xml.res.XMLMessages > -------------------------------------------------------------------- > > Key: XALANJ-1993 > URL: http://issues.apache.org/jira/browse/XALANJ-1993 > Project: XalanJ2 > Type: Bug > Components: Diagnostic-messages-resources > Environment: ibm jdk 1.3 and 1.4 > Reporter: Carlo Marchiori > > IBM jdks do not implements correctly the contract of the method > java.util.ResourceBundle.getBundle ().
