    Every minute or so, the AWI log shows these messages:

    The messages do not appear to be associated with any problems in the AWI. As far as I can tell, the AWI is working fine. Is there a way to prevent these messages from appearing?

    I cannot remember where I got the answer to this, but I think it was from CA Support. The answer was that the errors could be safely ignored, and that they would be removed in a future AWI version.

    we get this error on tomcat 8.5 and tomcat 9 but on tomcat 7 we have not received this error.

    I think the problem seems to be caused by tomcat version.
