The vlan mtu setting has no effect on intra-vlan packets, but rather on inter-vlan packets. So, if the VLAN mtu was set to the default 1500, but it received a packet from another VLAN destined for VLAN 22 in your example, it would not pass it because the SVI (interface vlan22) would not view it as a valid packet size.
If you were to do a sho int vlan22, you would see the VLAN mtu of 9000. Its confusing because it seems that you're making a VLAN setting in the VLAN database, but the effect is at the VLAN's SVI, not on each port that is a member of the VLAN. In the 3750, you can only set the MTU size for switch ports globally for the whole switch. You can't set only ports in a certain VLAN, and you can't do it on a per-port basis. I believe you need the 6500 for that.
