Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError

Hi all,

I get this exception when I try to test a conditional goto:

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError                                                                                                               
        at com.eviware.soapui.impl.wsdl.submit.transports.http.BaseHttpResponse.getContentAsXml(BaseHttpResponse.java:272)                                                          
        at com.eviware.soapui.impl.wsdl.panels.teststeps.GotoStepDesktopPanel$RunAction.actionPerformed(GotoStepDesktopPanel.java:484)
.... more

A similar exception is raised when the step runs in the context of a test suite.

I am using soapUI 3.0.1 (soapUI-x32-3_0_1.sh)
java version "1.5.0_18"
linux 2.6.27-14-generic (Kubuntu)

Is anyone using a similar configuration and is able to use the conditional goto?
