Clarified the purpose of forcePass() and forceFail() methods and recommended usage of these methods.
forcePass() contained an incorrect sample; it's addressed by [JDK-8355441](https://bugs.openjdk.org/browse/JDK-8355441). The description of forceFail() has been expanded, too. A new section in the description of the PassFailJFrame added to describe forcePass() and forceFail(). ------------- Commit messages: - 8355515: Clarify the purpose of forcePass() and forceFail() methods Changes: https://git.openjdk.org/jdk/pull/25091/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=25091&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8355515 Stats: 31 lines in 1 file changed: 29 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/25091.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/25091/head:pull/25091 PR: https://git.openjdk.org/jdk/pull/25091
