[Res] Not being able to import WSDL's in SoapUI Pro 4.6.4

Hi,

we have a similar problem:
"Error loading [http://...?wsdl]: org.apache.xmlbeans.XmlException: java.io.CharConversionException: Malformed UTF-8 character: 0xdf 0x6"

And we also can avoid this error by changing the vmoptions file.
But I don't think the reason for the error is a missing encoding statement within the wsdl/xds files.
All files I checked do have this statement:
<?xml version="1.0" encoding="UTF-8"?>

So is this a bug, or isn't it?

Best regards
Nico
