Hi

I dont know where to post formal bugs or suspected bugs, so here goes:

I am using JBoss JMX Agent View, in version 4.0.2RC1 for Win XP Pro.

In the filter string text box, I simply typed:

*jb*.*ad*

And got this result when I pressed ApplyFilter:

type Exception report

message

description The server encountered an internal error () that prevented it from 
fulfilling this request.

exception

java.lang.ArrayIndexOutOfBoundsException: 10
        
org.jboss.mx.util.ObjectNamePatternHelper.patternMatch(ObjectNamePatternHelper.java:104)
        
org.jboss.mx.util.ObjectNamePatternHelper.patternMatch(ObjectNamePatternHelper.java:99)

        org.jboss.jmx.adaptor.control.Server.getDomainData(Server.java:52)

org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.doPost(HtmlAdaptorServlet.java:61)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
        
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:75)


Although far from serious, it does indicate a weakness that could lead to 
server failure under various circumstances, and possibly offers an opportunity 
to a malicious attacker.

Incidentally, it would be nice if the JMX Agent View page had a little section 
near the top that listed the version number etc of JBoss and perhaps Tomcat? 
that is running?
