testBindInstantFromJavaUtilDate fails on systems in the Pacific/Auckland time zone [SPR-16534]

[spring-projects-issues]

William Hoyle opened SPR-16534 and commented

The DateTimeFormattingTests.testBindInstantFromJavaUtilDate test fails if run on a machine with a default time zone of "Pacific/Auckland" (UTC+12/13 depending on the time of year).

To reproduce:

Force the time zone in spring-context/spring-context.gradle:

test {
    systemProperty 'user.timezone', 'Pacific/Auckland'
}

Run the test:

./gradlew :spring-context:test --tests org.springframework.format.datetime.standard.DateTimeFormattingTests

Results in:

> Task :spring-context:test FAILED

org.springframework.format.datetime.standard.DateTimeFormattingTests > testBindInstantFromJavaUtilDate FAILED
    java.lang.AssertionError at DateTimeFormattingTests.java:366

Good catch! We're enforcing the execution of that test within the GMT time zone now, manipulating TimeZone.getDefault() accordingly (since that's what that old Date constructor is relying on).
