API differences in Hibernate ORM 5.1 vs 5.3
by Gail Badner
Hi,
There were lots of differences in the compatibility report, so as a first
step, I've excluded packages/classes that I considered SPI, internal, or
"grey area". This reduced the the differences to a more manageable amount.
You can see a summary of the incompatibilities along with suggested
mitigation at [1].
The report is attached to [1], along with a zip with instructions for
running the report.
I believe there are some "false positives" in the report, and I have
documented them in the section, "False Positives?".
Feel free to comment on the article.
Thanks,
Gail

IP banned from forum
by Gunnar Morling
Hi,
Is anyone banning users from the forum? I am getting "A ban has been
issued on your IP address."
I don't think banning by IP is a good strategy as many users will have
dynamic IPs from their hoster's shared pool, so it's a random game to
hit an IP previously banned due to some other user's spam.
Thanks,

Hibernate organization membership on GitHub
by Yoann Rodiere
Hello,
As part of the move to Commonhaus, I'm currently going through our GitHub
setup, and I'm noticing we have a lot of users with extensive (and I mean
*extensive*, sometimes admin or even owner) access to our
organization/repositories, but who are no longer regular contributors.
Additionally, we also have organization members on GitHub who are not
technically Hibernate members: they have never actually contributed to
Hibernate, but are there for technical reasons, for example because they're
coworkers who helped out with some infrastructure issue.
While it's fine in principle, because we trust these people, it's very,
very far from security best practices. Account hacking happens, email
addresses get stolen, and the people using these GitHub accounts might one
day be an attacker instead of the person we trust.
According to Commonhaus' automated report, we're currently at 32 people
having admin rights on one Hibernate repository or another. Which I think
we can all agree is much more than necessary.
For that reason, I'd like to propose that:
1. *We create an "Alumni" team in our GitHub organization*, moving to that
team anyone who is actually a member, but hasn't contributed for... let's
say 2 years? Of course this isn't a permanent thing, and we can simply move
alumni back to the relevant team if they become active again.
2. *We move non-members out of our GitHub organization*, or to "external
collaborators" (that's a GitHub feature) if still necessary.
3. *We schedule yearly audits of our GitHub configuration* to review access
rights again in the future, and move people to the Alumni team as necessary.
Note moving people in and out of teams will get them notified, so I would
send another email directly to impacted people before/during the move, to
avoid this being seen as personal/insulting. It's really not.
*Thoughts, opinions, +1s?*

New CI machine preview
by Sanne Grinovero
You're all welcome to play with http://54.225.162.168/
however please keep these in mind:
- it's not the final machine: don't put too much effort in creating
nice build scripts as we'll reset it to clean state soon. We *might*
be able to store jobs defined so far, but we might choose not to.
- domain name should be coming: ci.hibernate.org ..not sure when, got
no replies so far from.
- authentication: just click on login, it will use OAuth2 to request
your identity via your GitHub account. Permissions to create new jobs,
edit existing jobs, run a build manually depend on your github account
be part of the Hibernate organization (or not, in which case you have
read only status)
At this stage I'd like to get a feeling if the hardware is powerful
enough, and also we need to select which other plugins we want to use,
I'm looking especially to:
- static analysis reports
- pull requests integration
both are relatively undefined, we can of course start simple and
improve later.. just checking this fits basic needs now.

JDK 25 feature set is now frozen!
by David Delabassee
Welcome to the June installment of the OpenJDK Quality Outreach update.
JDK 25, scheduled for General Availability on September 16, 2025, has entered Rampdown Phase One (RDP1)[1]. The JDK 25 feature set is now frozen (see JDK 25 details below), and only low-risk enhancements will be considered. Please help us identify potential issues in the coming weeks by testing your projects on JDK 25 EA builds. With enough lead time, we can resolve them before JDK 25 transitions to the Release Candidate phase in early August[2].
Be make sure to review the JDK 25 heads-ups below; two of them pertain to changes in file operations on Windows.
Last but certainly not least, you are invited to attend next week’s JCP EC online public meeting, where Alex Buckley will give a presentation on Tip & Tail Development—a topic particularly relevant for open-source project maintainers. See [3] for details, the meeting will be recorded.

# Heads-up - JDK 25: java.io.File.delete no longer deletes read-only files on Windows
`File.delete` has been changed on Windows so that it now fails and returns `false` for regular files when the DOS read-only attribute is set. Prior to JDK 25, `File.delete` would delete read-only files by first removing the DOS read-only attribute before attempting deletion. However, because removing the attribute and deleting the file are not a single atomic operation, this could result in the file remaining but with modified attributes if the deletion failed. Applications that depend on the previous behavior should be updated to clear the file attributes before deleting files.
To ease the transition, a system property has been introduced to restore the previous behavior. Running with `-Djdk.io.File.allowDeleteReadOnlyFiles=true` will cause `File.delete` to remove the DOS read-only attribute before attempting deletion, restoring the legacy behavior.
See https://bugs.openjdk.org/browse/JDK-8355954 for more details.
# Heads-up - JDK 25: File operations on Windows now always fail if the used name ends with a space
File operations on a path with a trailing space in a directory or file name, e.g. "C:\\SomeFolder\\SomeFile ", now fail consistently on Windows. For example. `File::mkdir` will return `false`, or `File::createNewFile` will throw `IOException` if an element in the path has a trailing space. Such pathnames are not legal on Windows. Prior to JDK 25, operations on a `File` created from such an illegal abstract pathname could appear to succeed when in fact they did not.
See https://bugs.openjdk.org/browse/JDK-8354450 for more details.
# Heads-up - JDK 25: Separate Metaspace and GC Printing
Historically the printing of Metaspace and GC logs have been combined; this was a result of permanent generation (PermGen) being a part of the GC Heap. However, Metaspace has replaced PermGen and resides in its own native memory location outside of the GC Heap. With Metaspace no longer a part of the GC Heap, the reason for combining the messaging no longer makes sense and could lead to confusion.
Starting with JDK 25, the way logging is tagged in the HotSpot JVM will change: although the content of the logs will remain the same, messages related to Metaspace will now use the existing Metaspace tag.
As part of this update, there are also some user-facing changes to `jcmd`. To better clarify that Metaspace is not part of the GC Heap, Metaspace information is no longer displayed with the `GC.heap_info` command. Instead, details about Metaspace memory usage have been moved to the `VM.metaspace` command.
See https://bugs.openjdk.org/browse/JDK-8356848 for more details.

# JavaFX 25 Early-Access Builds
These are early access builds of the JavaFX 25 Runtime, built from the openjdk/jfx repository. They enable JavaFX application developers to build and test their applications with JavaFX 25 on JDK 25. Although these builds are designed to work with JDK 25 EA, they are also compatible with JDK 22 and later versions.
The latest early access builds of JavaFX 25 Builds 18 (2025/5/23) are available[7], under the GNU General Public License, version 2, with the Classpath Exception. JavaFX 25 API Javadocs[8] are available too.

# JavaFX Direct3D 12 Early-Access Builds
These are early access builds of JavaFX from the "direct3d12" branch of the openjdk/jfx-sandbox repository[9], which implement the new Direct3D 12 graphics rendering pipeline for Windows x64. The goal of these EA builds is to solicit feedback as we work toward integrating this functionality into JavaFX. Binaries[10] are provided for convenience, so users do not need to build from source.
Feedback can be reported to the openjfx-dev mailing list[11]. These builds are provided under the GNU General Public License, version 2, with the Classpath Exception, and are based on an incomplete version of JavaFX 25.
