Open or Save button in JFileChooser has OK title in GTK LAF. The open/save button text modified as per the native FileChooser. Manual test case is added.
`open/test/jdk/sanity/client/SwingSet/src/FileChooserDemoTest.java` failed with the current fix with an exception `**Wait AbstractButton with text "OK" loaded.**` Updated the test for GTK LAF and tested in CI which is OK now. CI link is added in JBS. ------------- Commit messages: - Open/Save button text modified Changes: https://git.openjdk.org/jdk/pull/11790/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=11790&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8081507 Stats: 82 lines in 3 files changed: 78 ins; 0 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/11790.diff Fetch: git fetch https://git.openjdk.org/jdk pull/11790/head:pull/11790 PR: https://git.openjdk.org/jdk/pull/11790
