java.net.UnknownHostException adding a wsdl

Hello,

When I add a wsdl in a SOAP project the application returns java.net.UnknownHostException:
org.apache.xmlbeans.XmlException: java.net.UnknownHostException: (host_address)

But y put that wsdl address at iexplorer using a proxy and calls the wsdl correctly.

I have configured the same proxy at SOAPIU / Preferences / Proxy Settings.

I use the 4.6.4 soapUI version.
