stoty · 2025-09-15T08:49:59Z

Description of PR

Java 24 has changed the behaviour for HTTP short reads, and now throws an IOException.
Update the expected Exception for Java 24.

How was this patch tested?

Ran test with Java 8 and 24

For code changes:

Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?

PTAL @slfan1989 .

stoty · 2025-09-17T08:14:31Z

The test failures are pre-existing and not related to my changes.

stoty · 2025-10-27T11:15:51Z

Can you review this @slfan1989 ?
This test breaks on JDK24+.
