Null Pointer Exception #195

Closed AkBappy closed 5 years ago

AkBappy commented 6 years ago

After setting the environment, when I start the tomcat server, I get null pointer exception.

Thank you for the report, the developers are currently busy, they will reply later.

@AkBappy, thank you for reporting this issue. We are already aware of this situation (for our own reference, see task ZS-220). This null pointer exception should not be a problem for you as there is very little functionality that relies on the IEC61850 simulator.
