Error description

• When you use coaches, the user interface communicates with
  server-side code in the
  com.lombardisoftware.component.common.web.TWComponentWebUIImpl
  class. This server-side code insufficiently checks which can
  cause the NullPointerException to under load. In such cases
  there does not exist enough logging information. As a result,
  there is not enough trace information to analyze issues.
  Exception:
