did test it the last 15 Minutes (SA 7.2R1.1) and it does work, BUG is fixed.
problem reappears on IVE 7.2R3 .... Pulse Version: Junos Pulse 220.127.116.1195
HostChecker configured as following...
Juniper SA 7.2R3 in combination with following Pulse Client: Junos Pulse 18.104.22.16879 does work.
Juniper SA 7.1R10 in combination with the following Pulse Client: Junos Pulse 22.214.171.12479 doesn't work.
So it seems both components (Ive and Pulse) have to be on the latest release train.
