Yep, they could: I have the following:
+++
<IfModule mod_jk.c>
JkWorkersFile /usr/local/apache/conf/workers.properties
 
JkLogFile     logs/mod_jk.log
JkLogLevel    debug
 
JkMount  toto titi
JkMount  /examples/* examples
JkMount  /servlet-tests/* servlet-tests
JkMount  /jsp-tests/* jsp-tests
#JkMount  toto titi
</IfModule>
+++

And I have added a trace in map_uri_to_worker that shows:
+++
jk_uri_worker_map_t::map_uri_to_worker,00000000 0
jk_uri_worker_map_t::map_uri_to_worker,080d08b8 10
jk_uri_worker_map_t::map_uri_to_worker,080d0900 15
jk_uri_worker_map_t::map_uri_to_worker,080d0958 11
+++
I will try to fix the problem.
