Write a regression test for [JDK-4525475](https://bugs.openjdk.java.net/browse/JDK-4525475)
Issue: JFileChooser allows modification to the file-system by way of the "New Folder" button, and the ability to rename file/folder names. There is no method on JFileChooser which indicates that this type of modification should not be allowed within the given JFileChooser. Testing: 1. Tested using Mach5(20 times per platform) in macos,linux and windows and got all pass. 2. Tested in original failed Java version and the fixed version; Java 1.4.0 -> Test Failed. $ j2sdk1.4.0/bin/java Bug4525475 LookAndFeel: com.sun.java.swing.plaf.windows.WindowsLookAndFeel Name = Go Up, readOnly = true Name = New Folder, readOnly = true Its a Read Only JFileChooser and has a New Folder Button. So Test Failed. Name = Go Up, readOnly = false Name = New Folder, readOnly = false Failed Java 1.5.0 -> Test Passed. $ jdk1.5.0/bin/java Bug4525475 LookAndFeel: com.sun.java.swing.plaf.windows.WindowsLookAndFeel Name = Go Up, readOnly = true Name = Go Up, readOnly = false Name = New Folder, readOnly = false Passed ------------- Commit messages: - 8283623: Create an automated regression test for JDK-4525475 Changes: https://git.openjdk.java.net/jdk/pull/7969/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=7969&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8283623 Stats: 138 lines in 1 file changed: 138 ins; 0 del; 0 mod Patch: https://git.openjdk.java.net/jdk/pull/7969.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/7969/head:pull/7969 PR: https://git.openjdk.java.net/jdk/pull/7969
