Issue/Introduction

We're running Policy Server 12.8SP0 and this one doesn't seem to be

able to validate existing SMSESSION cookie in SP Initiated Post

transaction.

We see the following error in the Policy Server traces :

   [08/13/2018][09:57:49.227][09:57:49][532][139977941837568][AssertionGenerator.java]

   java.lang.Exception: The Federation Web Service didn't send the

   request with a correct resource! Internal Exception:

   java.lang.IllegalArgumentException: Input byte array has incorrect

We've tried also on our Policy Server 12.7SP2, and for the same

transaction this one returns similar error :
