Minborg provided a benchmark on string conversion using this API for JDK 21 and JDK 22 compared to using the old Java Native Interface (JNI) calls.
Build 13 of the JDK 22 early-access builds was also made available this past week featuring updates from Build 12 that include fixes to various issues. Further details on this build may be found in the release notes.
On the road to version 1.0, Oracle Labs has released version 0.9.25 of Native Build Tools, a GraalVM project consisting of plugins for interoperability with GraalVM Native Image. This latest release provides a dependency upgrade to GraalVM Reachability Metadata Repository 0.3.4. More details on this release may be found in the changelog.
Spring Framework
In their quest to solve the N+1 problem, the Spring Data team has introducedSingle Query Loading, a technique designed to load arbitrary aggregates with a single SELECT statement. Available with the release of Spring Data JDBC 3.2.0-M2, the team claims this new technique is the “beginning of the end for the N+1 problem.” A new method, setSingleQueryLoadingEnabled(true), has been added to the RelationalMappingContext class to enable Single Query Loading. At this time, this only works for simple aggregates, consisting of an aggregate root and a single collection of other entities, but the team promises that future releases will improve on this limitation.
Quarkus
Red Hat has released version 3.3.1 of Quarkus that ships with dependency upgrades and notable changes such as: a fix for a potential NullPointerException in the MicrometerRecorder class; a new counter, rejected, added to the VertxPoolMetrics class to count rejected requests; and a fix in which the VertxHttpExporter class incorrectly parses the /v1/traces endpoint. Further details on this release may be found in the changelog.
Similarly, Quarkus 3.2.5.Final has been released with notable changes such as: a fix for a potential NullPointerException in the Cross-Site Request Forgery extension when the CsrfRequestResponseReactiveFilter class is checking the media type; a disabling of the testMoreRepositoryFunctionalities() method in the ReactiveMongodbPanacheResourceTest class as it has been characterized as “flaky” according to the string passed-in to the @Disabled annotation; and a fix for a deadlock upon calling a write-locked method of a bean in multiple threads in which this method calls another write-locked method within the same bean. More details on this release may be found in the changelog.
And finally, the release of Quarkus 2.16.10.Final provides a dependency upgrade of Snappy Java from version 1.1.8.4 to version 1.1.10.1. Further details on this release may be found in the changelog.

DUBAI, United Arab Emirates (AP) — The tiny Mideast nation of Kuwait has banned the release of the video game “Call of Duty: Black Ops 6,” which features the late Iraqi dictator Saddam Hussein and is set in part in the 1990s Gulf War.
The video game, a first-person shooter, follows CIA operators fighting at times in the United States and also in the Middle East. Game-play trailers for the game show burning oilfields, a painful reminder for Kuwaitis who saw Iraqis set fire to the fields, causing vast ecological and economic damage. Iraqi troops damaged or set fire to over 700 wells.
There also are images of Saddam and Iraq’s old three-star flag in the footage released by developers ahead of the game’s launch. The game’s multiplayer section, a popular feature of the series, includes what appears to be a desert shootout in Kuwait called Scud after the Soviet missiles Saddam fired in the war. Another is called Babylon, after the ancient city in Iraq.
Activision acknowledged in a statement that the game “has not been approved for release in Kuwait,” but did not elaborate.
“All pre-orders in Kuwait will be cancelled and refunded to the original point of purchase,” the company said. “We remain hopeful that local authorities will reconsider, and allow players in Kuwait to enjoy this all-new experience in the Black Ops series.”
Kuwait’s Media Ministry did not respond to requests for comment from The Associated Press over the decision.
“Call of Duty,” which first began in 2003 as a first-person shooter set in World War II, has expanded into an empire worth billions of dollars now owned by Microsoft. But it also has been controversial as its gameplay entered the realm of geopolitics. China and Russia both banned chapters in the franchise. In 2009, an entry in the gaming franchise allowed players to take part in a militant attack at a Russian airport, killing civilians.
But there have been other games recently that won praise for their handling of the Mideast. Ubisoft’s “Assassin’s Creed: Mirage” published last year won praise for its portrayal of Baghdad during the Islamic Golden Age in the 9th century.

SAN FRANCISCO (AP) — Artificial intelligence‘s recent rise to the forefront of business has left most office workers wondering how often they should use the technology and whether a computer will eventually replace them.
Those were among the highlights of a recent study conducted by the workplace communications platform Slack. After conducting in-depth interviews with 5,000 desktop workers, Slack concluded there are five types of AI personalities in the workplace: “The Maximalist” who regularly uses AI on their jobs; “The Underground” who covertly uses AI; “The Rebel,” who abhors AI; “The Superfan” who is excited about AI but still hasn’t used it; and “The Observer” who is taking a wait-and-see approach.
Only 50% of the respondents fell under the Maximalist or Underground categories, posing a challenge for businesses that want their workers to embrace AI technology. The Associated Press recently discussed the excitement and tension surrounding AI at work with Christina Janzer, Slack’s senior vice president of research and analytics.
Q: What do you make about the wide range of perceptions about AI at work?
A: It shows people are experiencing AI in very different ways, so they have very different emotions about it. Understanding those emotions will help understand what is going to drive usage of AI. If people are feeling guilty or nervous about it, they are not going to use it. So we have to understand where people are, then point them toward learning to value this new technology.
Q: The Maximalist and The Underground both seem to be early adopters of AI at work, but what is different about their attitudes?
A: Maximalists are all in on AI. They are getting value out of it, they are excited about it, and they are actively sharing that they are using it, which is a really big driver for usage among others.
The Underground is the one that is really interesting to me because they are using it, but they are hiding it. There are different reasons for that. They are worried they are going to be seen as incompetent. They are worried that AI is going to be seen as cheating. And so with them, we have an opportunity to provide clear guidelines to help them know that AI usage is celebrated and encouraged. But right now they don’t have guidelines from their companies and they don’t feel particularly encouraged to use it.
Overall, there is more excitement about AI than not, so I think that’s great We just need to figure out how to harness that.
Q: What about the 19% of workers who fell under the Rebel description in Slack’s study?
A: Rebels tend to be women, which is really interesting. Three out of five rebels are women, which I obviously don’t like to see. Also, rebels tend to be older. At a high level, men are adopting the technology at higher rates than women.
Q: Why do you think more women than men are resisting AI?
A: Women are more likely to see AI as a threat, more likely to worry that AI is going to take over their jobs. To me, that points to women not feeling as trusted in the workplace as men do. If you feel trusted by your manager, you are more likely to experiment with AI. Women are reluctant to adopt a technology that might be seen as a replacement for them whereas men may have more confidence that isn’t going to happen because they feel more trusted.
Q: What are some of the things employers should be doing if they want their workers to embrace AI on the job?
A: We are seeing three out of five desk workers don’t even have clear guidelines with AI, because their companies just aren’t telling them anything, so that’s a huge opportunity.
Another opportunity to encourage AI usage in the open. If we can create a culture where it’s celebrated, where people can see the way people are using it, then they can know that it’s accepted and celebrated. Then they can be inspired.
The third thing is we have to create a culture of experimentation where people feel comfortable trying it out, testing it, getting comfortable with it because a lot of people just don’t know where to start. The reality is you can start small, you don’t have to completely change your job. Having AI write an email or summarize content is a great place to start so you can start to understand what this technology can do.
Q: Do you think the fears about people losing their jobs because of AI are warranted?
A: People with AI are going to replace people without AI.
