This PR fixes controls unit test failures that are observed with German locale.
Fix : Code added to use US locale while running SpinnerTest and DatePicker test & restore locale to default after these tests are executed. test.javafx.scene.control.ControlTest.testRT18097 fails for DatePicker control. Fixing DatePickerTest fixes this. This reveals the fact that our unit tests run in a single VM and any test that changes the Locale setting should restore it to the default at the end. ------------- Commit messages: - fix_controls_test_locale Changes: https://git.openjdk.java.net/jfx/pull/476/files Webrev: https://webrevs.openjdk.java.net/?repo=jfx&pr=476&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8264952 Stats: 29 lines in 2 files changed: 25 ins; 1 del; 3 mod Patch: https://git.openjdk.java.net/jfx/pull/476.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/476/head:pull/476 PR: https://git.openjdk.java.net/jfx/pull/476
