SQE OK to take the low risk fix to CPU15_01
14-11-2014
Critical request: - Justification: Regression which highly affects user experience. - Risk Analysis: Low, the fix gets the AppContext associated with the component rather than the AppContext associated with the thread. - Webrev: http://cr.openjdk.java.net/~pchelko/9/8043610/webrev/ - Review thread: http://mail.openjdk.java.net/pipermail/awt-dev/2014-May/007846.html - Testing (done/to-be-done): Automatic regression test is included. Sort JFileChooser columns in an applet or a WebStart application. - Back ports (done/to-be-done): Done - FX Impact: No
