Torsten commented on PLC4X-303:
-------------------------------
Hi,
if I want to specify an empty password by
"opcua:tcp://myhost:12686/milo?discovery=false&username=user&password=" or
"opcua:tcp://myhost:12686/milo?discovery=false&username=user&password"
the URL validation fails with
"Connection string doesn't match the format ..."
If I remove it from the URL
"opcua:tcp://myhost:12686/milo?discovery=false&username=user"
I got:
Caused by: java.lang.NullPointerException

Possible, instead of
byte[] passwordBytes = this.password.getBytes();
we should create an empty password?
byte[] passwordBytes = this.password == null ? new byte[0] :
this.password.getBytes();
