            Bug ID: 54170
           Summary: JMX ObjectName for Filters: names used without quoting
                    (escaping)
           Product: Tomcat 7
           Version: 7.0.26
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: benjamin.gehrels_external@immobilienscout24.de
    Classification: Unclassified

How to reproduce:
Execute 

context.addFilter("deprecatedApiReporterFilterFor/myAPI/v2/*, new
ArbitraryServletFilter()).addMappingForUrlPatterns(null, false, "/myAPI/v2/*");

from inside the contextInitialized-Method of an ServletContextListener.


What happens:
Nov 19, 2012 6:01:34 PM org.apache.catalina.core.ApplicationFilterConfig
registerJMX
Information: JMX registration failed for filter of type
[ArbitraryServletFilter] and name [deprecatedApiReporterFilterFor/myAPI/v2/*]

Caused by: java.lang.IllegalArgumentException: Repository: cannot add mbean for
pattern name
Catalina:j2eeType=Filter,name=deprecatedApiReporterFilterFor/myAPI/v2/*,WebModule=//localhost/,J2EEApplication=none,J2EEServer=none
    ... 24 more

Why does it happen:

Because ApplicationFilterConfig constructs the ObjectName by String
concatenation, without escaping the filterName using ObjectName.quote(String s)

I was able to reproduce it using Catalina 7.0.26.
