Error description

• Environment: Windows
  Product name: IBM Rational Business Developer
  
  Program Version    :  9.0
  Description.
  A JSON error is observed when a webservice returns a float value
  within a RUI application where the German locale has been
  applied.
  In German the decimal numbers are separated by a comma so the
  EGL runtime then adopts this representation within the JSON
  answer to a webservice call resulting in an incorrect format
  with float data types which throws an exception eg:
  An exception has occurred while calling
  http://localhost:9087/MyWebservices/restservices/myservices on
  method: testSmallFloat
  The body of the request was:
  {'bindingName':'Imyservices','method':'testSmallFloat','params':
  []}
  message:[CRRUI3655E] Fehler bei Verarbeitung des Antwortobjekts:
  '[CRRUI2089E] Die Konvertierung aus dem JSON-Format '{'result' :
  1,23}' war aufgrund von invalid object initializer nicht
  m?glich.'
  ServiceKind:REST
  detail1:200
  detail2:OK
  detail3:{'result' : 1,23}
  
  With English locale setting the same call will work correctly.
  
  NB: Reported in RBD v90 but its also reproducible with v901.
  Other languages are also effected where associated with the
  comma separator for example I see the same error with the French
  locale.

  ****************************************************************
  The smallfloat/float value is formatted in the Java service
  runtime within German locale and then return back to the
  service caller, which causes an invalid JSON string.
  

Problem conclusion

• Changed the Java service runtime to not automatically format
  the smallfloat/float value.
