Updated OS X Lion (10.7.2) with the Java update from Apple via Apple's network update tool last night. It broke the Juniper Network Connect VPN client application. Someone is also reporting that the Java update on 10.6.8 also broke this. I've confirmed on two different Lion macbook pros. Behavior is:
Network Connect starts up and is able to contact the remote server. It accepts my login credentials and passes the host check that our servers do, but instead of then providing our usual prompts/links window to select VPN, etc., the Network Connect window gets put behind other windows and returns to the prompts for login credentials.
I can also confirm that launching from the web portal rather than the local installed Network Connect client works, So, I have a workaround, but the Network Connect functionality is currently broken by the Java update.
The Network Connect log file is indicating a bus error core (signal 10):
