The summary is a bit misleading - I only know this is true for the httpd_catalog, but fo that code, this is definitely true and I suspect it's true for CMR as well (but I'm less sure how to test that code).
Given the httpd_catalog's default configuration (and making sure that is altered to activate the catalog), asking for <showNode> response for the following paths produces:
(note the presence or absence of trailing slashes)
/RemoteResources/tests/ --> Correct response, with <node count="2" ... name="/RemoteResources/test">
/RemoteResources/tests --> basic_string C++ exception
Reopen - my fix appears to break stuff when actually getting remote resources. HK-313 branch restored on GitHub
