Java crashes on WiFi only (Opera PMS)

[seashells]

We have a very odd problem when using OPERA PMS - Whenever we try to open a submenu java crashes with errors such as 'java.net.UnknownHostException...' and 'WARNING: Unable to cache...' - the laptop is running Windows 10 and interestingly only when its connected to WIFI - on cable it works without problems. There is full visibility between the laptop and the Opera server and both can ping eachother by DNS/IP. Thanks

conceivable the wireless is corrupting a portion of the packet headers. tried a driver update? Ive see stupid things like this with out of date router / AP firmware too.

If you change the Java security level does the message go away?

I'd check the IP settings for the WI-FI connection. The message is pretty clear: the host cannot be reached. It's typical that your laptop is inside the domain when connected to cable and uses a proxy when connected to WiFi, so it can't reach "operasrv01@

From the log I see you are using JRE version 1.3.1.25. Is there a reason for that? It's a little bit outdated (2005)
