Issues occur when you try to access instances from the SAS Infrastructure for Risk Management user interface (UI) when the logged-on user contains a user ID with special (@) characters. As a result, an illegal argument exception occurs when you create the region as part of Apache Geode. 

In addition, the following error occurs in the SASServer8_1 server.log file on the middle-tier machine:

<SASConfig>/<Lev#>/Web/WebAppServer/SASServer8_1/logs/server.log
