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,

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 18 Early-Access builds 23 are available
by David Delabassee
Sanne & Yoann,
I’m happy to announce that moving forward Oracle’s Java DevRel Team will manage the Quality Outreach Program. I would like to thank Rory for all the efforts he's put into this program and wish him all the joy and happiness that retirement can bring! We have big shoes to fill but we’re excited to continue building off the amazing structure Rory has put in place.
The JDK 18 schedule is now known [1] with a feature freeze date (Rampdown Phase One) less than 4 weeks away! This time, we have 2 important heads-ups, one related to JEP 411 (Deprecate the Security Manager for Removal), and one related to JEP 416 (Reimplement Core Reflection with Method Handles). We're asking your help to test and confirm that your project works seamlessly now that those 2 JEPs are integrated in the JDK 18 Early-Access builds.
[1] https://openjdk.java.net/projects/jdk/18/
# JEP 411 - Deprecate the Security Manager for Removal
Starting JDK 18 b21 [2], the default value of the 'java.security.manager' system property is set to "disallow". This means that any application or library that enables the Security Manager by calling `System.setSecurityManager` will now have to specify `-Djava.security.manager=allow` on the command-line in order for that code to continue working as expected. This change was originally targeted for JDK 17, but after some discussion/feedback from the community, the change was delayed until JDK 18 [3].
[2] https://bugs.openjdk.java.net/browse/JDK-8270380
[3] https://openjdk.java.net/jeps/411#Description
# JEP 416 - Reimplement Core Reflection with Method Handles
JEP 416 [4] reimplements `java.lang.reflect.Method`, `java.lang.reflect.Constructor`, and `java.lang.reflect.Field` on top of `java.lang.invoke` method handles. Making method handles the underlying mechanism for reflection will reduce the maintenance and development cost of both the `java.lang.reflect` and `java.lang.invoke` APIs. This is solely an implementation change but we encourage you to test your project to identify any behavior or performance regressions.
