  An application is attempting to read post data from the input
  stream, but the server has already closed the input stream.
  This produces an FFDC with an exception similar to the
  following:
  Exception:java.lang.NullPointerException
  SourceId:HttpInboundLink.handleDiscrimination
  ProbeId:1
  Reporter:com.ibm.ws.http.channel.inbound.impl.HttpInboundLink
  java.lang.NullPointerException
  at
  com.ibm.ws.webcontainer.channel.WCCByteBufferInputStream.complet
  eRead(WCCByteBufferInputStream.java:138)
  at
  com.ibm.ws.webcontainer.channel.WCChannelLink.writeBuffer(WCChan
  nelLink.java:429)
  

Problem conclusion

• The Webcontainer has been modified to avoid the
  NullPointerException.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.0.0.12 and 8.5.5.8.
