I want to parse the following String into an OffsetDateTime:

OffsetDateTime test = OffsetDateTime.parse("2021-12-31T23:00:00.000+00:00");

However, this results in an exception:

java.time.format.DateTimeParseException: Text '2021-12-31T23:00:00.000+00:00' could not be parsed: null at java.base/java.time.format.DateTimeFormatter.createError(DateTimeFormatter.java:2017) ~[na:na] at java.base/java.time.format.DateTimeFormatter.parse(DateTimeFormatter.java:1952) ~[na:na] at java.base/java.time.OffsetDateTime.parse(OffsetDateTime.java:402) ~[na:na]

I have seen answers online where this worked right away and I have tried creating custom formatters, but these return the same error message:

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ"); OffsetDateTime test = OffsetDateTime.parse("2021-12-31T23:00:00.000+00:00", formatter);

I am using Java 11.0.17 on Windows.

Update: It works on colleagues machine, but not mine. It also does not work when I select a different Java version in IntelliJ.

Here is the complete Stacktrace (I added it somewhere randomly in the existing project as the quickest way to test it). The stack trace is from Java 19 where a bit more information is given.

    I cannot reproduce this (Java (Temurin) 11.0.17 Windows 11). Commented Nov 25, 2022 at 12:02

    @Fenio The error reports Text '2021-12-31T23:00:00.000+00:00' could not be parsed, which means the input was not null. I'd sooner guess there might be some non-printable character in there or something (though if I try that, I get a different error). Commented Nov 25, 2022 at 12:04

    @f1sh How would that answer the question? The code as given in this question is correct and works fine on my machine. Commented Nov 25, 2022 at 12:06

    Related: DateTimeParseException: fails on one host, works on another, same JDK (no resolution though), I wonder if it is somehow related to bugs.openjdk.java.net/browse/JDK-8226704, but that bug is a lot older than Java 11.0.17 and is marked as resolved. However, this might suggest that the problem might be related to Locale settings on your machine. Commented Nov 25, 2022 at 12:15

    What is the output of System.out.println(java.util.Locale.getDefault()) on your machine? What is the configured region in your windows region settings, (e.g. the "Regional format") Commented Nov 25, 2022 at 12:20

Reset to default

We found the problem:

The call was made inside an integration test where LocalDateTime::now was mocked. By default, MockedStatic does not keep the other methods, so things like LocalDateTime::of just return null (very unintuitive design decision imo). Behind the scenes, the parser obviously calls a method by LocalDateTime, resulting in this weird error. Changing Mockito.mockStatic(LocalDateTime.class) to Mockito.mockStatic(LocalDateTime.class, Mockito.CALLS_REAL_METHODS) fixed the problem.
