java.util.ConcurrentModificationException

           Summary: java.util.ConcurrentModificationException
           Product: Tomcat 5
           Version: 5.0.24
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: petteri.stenius@ubisecure.com


I sometimes see ConcurrentModificationException during Tomcat startup.

This issue was previously reported as #22388 for TC 5.0.7. The issue was 
marked as resolved! Any instructions how to work around this startup problem? 

Tomcat was installed from jakarta-tomcat-5.0.24.zip, the host is running J2SE 
1.4.2_02.
