SoapUI is a great tool for testing web services and works especially well with its automation features. I've been using this tool since as long as I can remember working in the IT industry, only recently moving some of the work over to newer tools like Postman. So even to this day SoapUI remains my primary testing tool. Unfortunately some time during the 5.2 release of SoapUI a number of plugins were installed that were meant for its Pro features, and now some of these plugins are incompatible with later versions of SoapUI and cause a number of exceptions to be logged while using the Test Runner.

The exception that is thrown is a ClassNotFoundException thrown when SoapUI is trying to load some of the plugins.




Even though this exception looks menacing, the Test Runner is not adversely impacted. The tests run...


...and complete without issues.


Yet the logs are filled with these pesky exceptions. So what can be done about them? Simply put - don't load those plugins! The plugins are found in the .soapuios/plugins directory under the home directory for the user (i.e. ~/ or C:\Users\ depending on your OS).

To disable loading of these plugins, rename the plugins directory to something like disabled_plugins. Easy. SoapUI will not be able to load these plugins now and the logs will no longer be filled with unnecessary exceptions!
