Errors when trying out the demo

[anna-seppala]

Hi, I've just downloaded your project and get errors when trying out the demo. When launching the docker image, I get the following output:

$ sudo ./start_demo.sh

Got the stub for HelloInterface
ActivationServer ready on port 1099...
Plain Server ready on port 1099...
RMI-IIOP Server ready on port 1050...
SSL Server ready on port 1100...

The stack trace looks scary but the servers are up and I can scan them with nmap.

When I then try to use rmiscout to connect to port 1099, I get this:

$ ./rmiscout.sh wordlist -i demo/wordlist.txt -n ActivationServer 127.0.0.1 1099

A similar thing happens with the registry 'plaintest'. Listing of the regirstier works even tough the same error gets shown:

$ ./rmiscout.sh list 127.0.0.1 1099

	name[1] = plaintest

My JAVA_HOME is /opt/jdk1.8.0_301 and the build of rmiscout was successful. What could be the issue?

Loads of thanks for your help!
