Ok, I have this same problem and even though I don’t have a fix I have some interesting information. The problem occurs on my second https request every time. A SOAPUI restart is required to make it go away. I downloaded the src to see if I couldn’t figure out the problem. Here is the interesting part, if I run so the application from the main method in eclipse the problem never occurs. And what is the difference? The only thing I can see is that my eclipse is starting in java 1.5 and not 1.6. So, maybe that can get someone pointed down the right path.
