I'm on the 4.3.1 tag.
I'm running a specific configuration. Maven project with multiple modules and specific profiles for some modules (btw i had to forge the url to access this feature)
The issue is here, i think. My first module loads the rule but doesn't use it; the second one gets it from the cache and try to accesses the params from the rule with an not a valid session anymore
