Hi,

I found this problem during a test session, using OPC UA Java SDK version 2.0.0.194.
My OPC UA client application was connected to a Kepware 5 server, and I moved the Windows date from 19 December 2014 to 26 December 2014, to simulate a week change.

My application raised this error :

After this stacktrace, all the read/write operation raised errors : i had to disconnect and reconnect to Kepware server to solve them.

My question is : can i intercept the security token timeout at code side, and force disconnect and reconnect automatically?
Because, this can be a great problem during the next time change day (28th march 2015).

Thanks
