I've been using sqldev in a citrix xenapp env for years...
O/P from current citrix receiver "Support Info" button:

Perhaps if you stated what specific "troubles" you are actually experiencing, people may be able to help.
SQL Developer works for most of our users but for one it always crashes after few minutes.
Thanks for you message, I'll escalate to my own support.
