Torsten commented on PLC4X-303:
-------------------------------

Hi Ben, You have pointed to the right thing: the milo server does not binds to 
localhost. If I use the hostname it will connect. Thank You very much.
Two notes:
1. the boolean field "ns=2;s=HelloWorld/ScalarTypes/Boolean" is returned as '0' 
(in 0.8.0 it is returned as 'false')
2. if I provide wrong credentials in the URL, the app will hang in call of new 
PlcDriverManager().getConnection( connectionString ) and never come back.
