Fix packs for DataPower Gateway version 2018.4.1
Fix packs for DataPower Gateway version 10.0.x

APAR status

• Closed as program error.

Error description

• Byte Order Marker (BOM) is used to determine the encoding of
  the payload.
  If the BOM is not delivered in a single TCP packet
  and is split among multiple packets and those packets are
  not joined by underlying OS before passing to DataPower, parsing
  of
  the payload will fail with the following error message for utf16
  payloads.
  
  Incomplete mark up or missing element at offset 0
  

Local fix

• * simple workaround for service with rule 1st action being
  xform action with input context INPUT:
  - change request type
  from XML (or SOAP) to Non-XML
  
  
  * Workaround if 1st action is
  not xform action with input context INPUT:
  
  - change service
  XML or SOAP request type to Non-XML
  
  - add
  INPUT-GWS(store://identity.js)-input as first rule action
  
  -
  change all actions with "INPUT" input context to use "input"
  context instead
  

Problem summary

• DataPower might not parse UTF16 XML if Byte Order Mark (BoM) is
  split on different TCP packets.
  

Problem conclusion

• Fix is available in 2018.4.1.12 and 10.0.0.1
