Did you try with the latest jk version (1.2.28)?

Not sure, what exactly works with ruby, but mod_jk doesn't know anything
about SetEnvIf and negative look ahead. It only checks, whether the
"no-jk" Apache environment variable is set, and if so, it doesn't
forward the request and instead lets Apache handle it itself.

You can check the value of "no-jk" by adding %{no-jk}e to your LogFormat
used in the CustomLog.

You can use mod_rewrite for such things. Mod_rewrite can check for file
existence and can also use back references when setting env vars.
