I'm trying to cleanup issues in libapache2-mod-jk package and this issue 
popped up on my radar :)

I can confirm that there was a change/fix in upstream handling of JkMount "copy" 
from global scope to VirtualHost in 1.2.26.
From upstream changelog [1], there was a SVN revision [2] that "add new value 
"All" for JkMountCopy directive and this will switch the default of 
JkMountCopy from Off to On for all virtual servers."

So previously (< 1.2.25) having a JkMount directive inside your global scope 
should have copied this to every child virtualhost. 1.2.26 fixed this issue and 
now provide a way to enable your expected behavior :
- set JkMountCopy All in you global scope
- set JkMountCopy On in each VirtualHost where you want to enable global scope 
JkMount

I'll had some warning/docs regarding this into libapache2-mod-jk in unstable.
