Personally I would log this as a bug org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:844) should *not* be allowing nulls as string
Anyone else ??

Hi, Sebastien.
This might be caused since Struts logs what bean it created and is going to populate. Turn off the RequestProcessor's log4j category and the call to toString() should be gone.
