According to #3 "Java Applet Continues to Load" from http://aseng-wiki.us.oracle.com/asengwiki/display/ASUsability/Java+Deploy+Certificate+Revocation+Flow#JavaDeployCertificateRevocationFlow-Issues, the java loading animation should stop once revocation dialog shows up.
Also according to https://jbs.oracle.com/bugs/browse/JDK-8010247 and https://jbs.oracle.com/bugs/browse/JDK-8013458, this issue should be fixed in jre7u40 and jre8.

But with latest jre8 pro build b102 and latest jre7u40#55, this issue is till there.

steps to reproduce:
1 Make sure there is a valid proxy set in your browser
2 Open JCP->Advanced->"Check for certificate revocation using": Check "Both CRLs and OCSP"
3 Launch singed applet whose jar is singed with a revoked cert: http://localhost:8080/OcspAndCrlCheckManual/html/testOCSPAndCRLRevokedCert.html
4 There will be a revoked dialog with title "Application Blocked for Security" shown up
5 If the java loading animation doesn't stop when revoked dialog shows up, then this bug is reproduced.

Expected behavior:
The Java loading animation should stop immediately in the background when revoked dialog shows up and "Application Blocked. Click for Details" should appear in the applet area.
But actually it stops and shows "Application Blocked. Click for Details" after clicking "OK" on revocation dialog.
