    Hi,

    I apologize for the slow response. We've seen your issue, but investigation is proving to be a bit difficult. We're working on it, and we'll get back to you as soon as possible.

    Regards,

    Hi,

    These are normally not something you have to worry about. I am assuming you are using a mock war deployment right?
    SoapUI does all sorts of things with both class loaders and threads that you would normally not do in a production class web application.

    If you run into actual memory leaks with out of memory errors occurring then it may actually be a leak.
    If you are worried I suggest you simply schedule a nightly restart of the Tomcat but I don't think there is much to worry about.
