Unable to establish connection via TLSv1.2 protocol in SoapUI 5.1.2

Hi,

I need to connect a webservice which only accept a connection established via TLSv1.2. I added the line

-Dsoapui.https.protocols=TLSv1.2 in the file SoapUI-5.1.2.vmoptions and still not able to establish the connection. Following message is displayed: "Error getting response; javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure"

I tried doing same on different version of SoapUI 4.6.1 and it works, is there any additional settings in 5.1.2. Also by default there is no entry in the vmoptions file, so in this scenario what is the protocol version it is using.

Any help is highly appreciated.

Thanks
