What's the Default Version of SSL and TLS Used by SoapUI

All,

I'm trying to run against two endpoint for comparing data.  One uses TLS 1.2 now.  When I use the option -Dsoapui.https.protocols=SSLv3,TLS1.2 the TLS endpoint works, but other endpoint fails.  I can used the other endpoint with no Dsoapui entry in VMOptions.  I cannot seem to find the protocols to make both endpoints happy.  Is there a solution to this and what is the default values SOAPUI uses?  I've also tried:

SSLv3,

SSLv3,TLS1.1

SSLv2

SSLvs,TLS1.2

None work.  Can I only have one protocol?

Thanks!
