Consistent JasperException observed in Log file of Production.

Error Messages

Servlet Exception occurred rendering diagnostics for client:org.apache.jasper.JasperException: java.lng.NullPointerException.

Steps to Reproduce

Not Applicable

Root Cause

1. Usage error logs in when browser connects: the solution is to update AuthenticationUtil.showStream() method of to conditionally pop Executable only when it is newly created in this method.

2. JasperException: cookies were not cleared when Security Violation Exception was thrown. Solution i sto clear the Pega-RULES cookie when rendering Security Violation Exception. Also, display an information status page instead of error status page, when you do not suspect a hacker attack
