steps:

1. EXEC: open new connection wizard
2. EXEC: in server use *https://open.paas.redhat.com*
3. EXEC: hit retrieve link
4. ASSERT: dialog shows up where you should accept the self-signed certificate
   
5. EXEC: check always trust "open.paas.redhat.com" & hit Continue

Result:
The dialog shows up again with the always trust "open.paas.redhat.com" unchecked. It doesnt seem to matter if you check it: the dialog shows up again and again and again and again...
