Refactor the test `javax/swing/JButton/TimeChangeButtonClickTest.java` to use the `PassFailJFrame` framework to handle the tester's decision on whether the test passes or fails.
I reformatted the instructions for performing the test into HTML. I preserved the test UI panel which contains the button to press and the label with button press counter. The updated test is shorter by nearly 100 lines. ------------- Commit messages: - 8341984: Use PassFailJFrame for TimeChangeButtonClickTest.java Changes: https://git.openjdk.org/jdk/pull/21476/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=21476&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8341984 Stats: 175 lines in 1 file changed: 11 ins; 105 del; 59 mod Patch: https://git.openjdk.org/jdk/pull/21476.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/21476/head:pull/21476 PR: https://git.openjdk.org/jdk/pull/21476
