Every secondary effect of a crit should still be applied if the crit is removed due to the opponents resilience (said in blue post).
However i cant say that i have ever seen imp-sb's shadow vulnerability been applied on a target from a non-crit.

have any one here seen it happen or is this just flat out not working?

oh ok, i just missunderstood it then.
But resilience is still pretty gamebreaking for alot of spec/gear setups since there isnt any counter for it :-/

edit. Well its not the resilience by itself, its that combined with the min/maxing of 12stm jewels that can just obliterate glasscannon style of play :-)

Every defensive reaction to a crit should still be applied, e.g. Blessed Resilience, Blessed Recovery, Martyrdom, and so on. This is to avoid penalizing players for stacking resilience by reducing the other defenses that they've specced into. This does not hold true for offensive consequences of a crit - if resilience negates a crit, it will not proc Deep Wounds, Ignite, or Improved Shadowbolt, for instance. This also applies to attackers' passive abilities, such as Flurry and Seal Fate - what you see is what you get.

As a general rule, if it's an ability of the player doing the critting, the attack actually needs to critically strike for any "on crit" effects to come into play. If it's a crit-triggered ability of the player being crit, that's when resilience can negate the crit but still give them their proc.
