docs: Capture information about this problem into the incidentStream
  
  @param t          The exception which triggered the FFDC capture process.
  @param is         The IncidentStream. Data to be captured is written to this stream.
  @param callerThis The 'this' pointer for the object which invoked the filter. The value
  will be null if the method which invoked the filter was static, or if
  the method which invoked the filter does not correspond to the DM
  being invoked.
  @param objs       The value of the array may be null. If not null, it contains an array of
  objects which the caller to the filter provided. Since the information in
  the array may vary depending upon the location in the code, the first
  index of the array may contain hints as to the content of the rest of the
  array.
  @param sourceId   The sourceId passed to the filter.
