FULL PRODUCT VERSION :
Java Plug-in 11.5.2.13
Using JRE version 1.8.0_05-b13 Java HotSpot(TM) Client VM

EXTRA RELEVANT SYSTEM CONFIGURATION :
Windows OS, SQUID proxy with username / password authenticaton. NTLM is supported. 

A DESCRIPTION OF THE PROBLEM :
neither OCSP nor CRL based code signing certificate revocation check are not working behind authenticated proxy. 



THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Did not try

REGRESSION.  Last worked in version 8u5

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- ensure that either signer revocation check or full certificate revocation check is active in JCP advanced settings
- Applet is signed with a valid signer certificate (issued by Comodo) 
-CA is trusted
- Workstation is protected by proxy which requires autentication
-Applet loads with security prompt: "unable to ensure the certificate used to identify this application has not been revoked"

EXPECTED VERSUS ACTUAL BEHAVIOR :
- proxy authentication window is presendet OR
- browser proxy authentication is used OR
- Java proxy autentication presets and saved data is used

Domain policy restrict users to override default java security settings. Applet is not usable despite buying a legitimate code signing certificate.
