Context with %2F in name causes tomcat crash on shutdown

Several years ago I worked on integrating tomcat 5.5 into our web application management infrastructure.  During the process I fixed several tomcat 5.5 bugs, but apparently never sent the fixes upstream.  Oops.

Our application needs to be deployed to create a URL that looks like this:


I worked with several people on IRC to get tomcat5.5 to do this.  We had previously been using the path= parameter in the context xml file element with tomcat 4.1.  Unfortunately, it appears this feature was removed from tomcat5.5, and tomcat5.5 does not recurse into subdirectories when reading .xml context files.  The recommendation on IRC (after several suggestions which would not work for our environment) was to put %2F in the context xml file's name.  Such as this


This does work, however when you try to shutdown tomcat 6.0.18, you will get this crash:

Proposed patch
Comment 2 Joe Kislo 2008-11-21 08:36:13 UTC
I have attached a patch that I have been using to work around this issue. It modifies findChild to decode the name if the initial lookup fails.
Comment 3 Mark Thomas 2008-11-21 08:45:56 UTC
The correct way to do this in 6.0.18 is to use the # character rather than %2F.

%2F should be interpreted literally.
Comment 4 Mark Thomas 2008-12-26 15:51:04 UTC
This has been fixed in trunk. I want to do some more testing of this and look at bug 46262 before proposed anything for 6.0.x
Comment 5 Mark Thomas 2008-12-28 15:59:35 UTC
*** Bug 46262 has been marked as a duplicate of this bug. ***
Comment 6 Mark Thomas 2008-12-28 16:03:37 UTC
I couldn't break my fix in my testing so I have proposed the fix for 6.0.x
Comment 7 Mark Thomas 2009-01-31 00:42:50 UTC
This has been fixed in 6.0.x and will be included in 6.0.19 onwards.
