As the comment in the test case mentions, "Tests require that default locale is en_US." The default locale is required by the objects created in the static method `implementations`, marked with the JUnit annotation `@Parameterized.Parameters`. So the static method `initDefaultLocale`, marked with the JUnit annotation `@BeforeClass`, calls the method to set the required default: `Locale.setDefault(Locale.US)`.
The problem occurs because the `@Parameterized.Parameters` method is called before the `@BeforeClass` method, so the system locale is used as the default instead of `Locale.US`. The fix is to move the call to the first instruction of the `@Parameterized.Parameters` method so that the default is set before it's required. ------------- Commit messages: - 8264061: LocalDateTimeStringConverterTest fails in Canada Changes: https://git.openjdk.java.net/jfx/pull/438/files Webrev: https://webrevs.openjdk.java.net/?repo=jfx&pr=438&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8264061 Stats: 4 lines in 1 file changed: 0 ins; 3 del; 1 mod Patch: https://git.openjdk.java.net/jfx/pull/438.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/438/head:pull/438 PR: https://git.openjdk.java.net/jfx/pull/438
