  ****************************************************************
  This error happens in On Demand Router --> On Demand Router
  Properties --> Routing policy HTTP rules -->
  SubExpressionBuilder.
  When using the SubExpressionBuilder, routing polcy rules
  that contain special characters cause the server to
  generate Error 500 in the RulseCollection.do file. The Java
  Message report given is java.lang.IllegalArgumentExcpetion.
  In this case, a rule containing a % sign would properly
  validate and appear to be saved. When a user
  attempts to append a new rule to this existing rule set,
  however, the request would fail.
  

Problem conclusion

• Debugging revealed a code defect where several URLs were not
  being properly encoded. This update includes the encoding fixes
  that make it possible to include special characters as part of
  HTTP routing rules.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.4.  Please refer to the Recommended Updates
