Created attachment 244985 [details] Sources for an applet which sends requests throughout the applet life cycle and outputs cookies When an applet sends a request during applet teardown in the stop() or destroy() methods, the requests will not contain browser managed session cookies. The issue has been reproduced using Chrome 39 and Safari 8.0. It does not appear to be an issue with Internet Explorer 11 or Firefox 34. I've attached sources for an applet and servlet that can be used to reproduce the issue. Here's the Java console log with applet output and logging turned up: basic: Applet loaded. basic: Applet resized and added to parent container basic: PERF: AppletExecutionRunnable - applet.init() BEGIN ; jvmLaunch dt 2071822 us, pluginInit dt 3468065 us, TotalTime: 5539887 us basic: Applet initialized basic: Starting applet basic: completed perf rollup Applet Start Querying session to create if necessary Cookies before sending request network: Cache entry not found [url: http://localhost:8080/testsession/login, version: null] network: Connecting http://localhost:8080/testsession/login with proxy=DIRECT network: Connecting http://localhost:8080/ with proxy=DIRECT network: Server http://localhost:8080/testsession/login requesting to set-cookie with "JSESSIONID=CC22D1BCA967E61F8CD89415E58C4389; Path=/testsession/" cache: http://localhost:8080/testsession/login is not cacheable.
