soapUI-Pro-4.5.1 kept on freezing on me intermittently on my MacBook Pro. The cause of the problem is the jxbrowser browser component. To fix it, do the following:
- Close/kill soapUI
- /Applications/SmartBear/soapUI-Pro-4.5.1.app > Show Package Contents
- Edit /Applications/SmartBear/soapUI-Pro-4.5.1.app/Contents/Resources/app/bin/soapui-pro.sh
- Uncomment "JAVA_OPTS="$JAVA_OPTS -Dsoapui.jxbrowser.disable=true"
- Start soapUI
Hope this helps.
