This means stack traces on VM panics now should work properly also on FreeBSD/Aarch64 as well as Amd64. (Possibly also the other BSD's, but someone will have to verify that.) Along with some other BSD related fixes and refactorings backported from mainline, I think version 24.0.2 will be the most solid OpenJDK for FreeBSD so far. It's still not on par with the platforms supported by upstream, but we're slowly getting closer. #<a class="" href="https://hub.volse.no/search?tag=FreeBSD" rel="nofollow noopener" target="_blank">FreeBSD</a> #<a class="" href="https://hub.volse.no/search?tag=OpenJDK" rel="nofollow noopener" target="_blank">OpenJDK</a> #<a class="" href="https://hub.volse.no/search?tag=programming" rel="nofollow noopener" target="_blank">programming</a>

Harald Eilertsen Over the past seven months I've been working on <a href="https://freebsdfoundation.org/project/improving-openjdk-on-freebsd/" rel="nofollow noopener" target="_blank">improving the support for FreeBSD in OpenJDK</a>, sponsored by the @<a href="https://mastodon.social/@FreeBSDFoundation" rel="nofollow noopener" target="_blank">FreeBSD Foundation</a>. <pre><code>============================== Test summary ==============================    TEST                                              TOTAL  PASS  FAIL ERROR  SKIP >> jtreg:test/hotspot/jtreg:tier1                     3033  2720     9     0   304 << ==============================</code></pre> When I started on this project, we had about 100 failing Hotspot tests on FreeBSD, in addition to around 40 in the rest of the JDK. Getting below 10 in total (on x86_64) feels like a significant milestone, and worthy of a bit of celebration! :party_popper: It's been an interesting, and very educational ride. Some of those tests were pretty easy wins, but some required delving deep into the internals of both OpenJDK and FreeBSD, as well as getting acquainted with the basics of the ARM architecture and instruction set. (Remembering how fascinated I was when the <a href="https://en.wikipedia.org/wiki/Acorn_Archimedes" rel="nofollow noopener" target="_blank">Acorn Archimedes</a> was launched, I'd say this was long overdue!) I finally feel that the OpenJDK BSD port is nearing a state where it makes sense to try to upstream it, and get it fully integrated into the OpenJDK infrastructure and build/test/CI frameworks. There's still a lot of work remaining to get there, it has to be done in portions and with the cooperation of the upstream project, but I hope to be able to spend the next six months or so to get there. Thanks a lot to the welcoming and supportive OpenJDK developer community, as well as the @<a href="https://mastodon.social/@FreeBSDFoundation" rel="nofollow noopener" target="_blank">FreeBSD Foundation</a> and the people there for sponsoring and supporting the project, and for providing help and insights about the FreeBSD internals when I got stuck. #<a class="" href="https://hub.volse.no/search?tag=OpenJDK" rel="nofollow noopener" target="_blank">OpenJDK</a> #<a class="" href="https://hub.volse.no/search?tag=java" rel="nofollow noopener" target="_blank">java</a> #<a class="" href="https://hub.volse.no/search?tag=FreeBSD" rel="nofollow noopener" target="_blank">FreeBSD</a> #<a class="" href="https://hub.volse.no/search?tag=BSD" rel="nofollow noopener" target="_blank">BSD</a> #<a class="" href="https://hub.volse.no/search?tag=programming" rel="nofollow noopener" target="_blank">programming</a> #<a class="" href="https://hub.volse.no/search?tag=mywork" rel="nofollow noopener" target="_blank">mywork</a>

Peter TribblePerhaps the major annoyance is the complaints about non-serializable members of a serializable class. Because everything in swing insists on being serializable, but interfaces (which you're supposed to use instead of concrete classes, right?) can't be. I can't see any reason I would ever be interested in java serialization for my projects, so I'm just silencing the compiler - and javadoc (as it wants a comment for every field in a serializable class).<a href="https://mastodon.social/tags/openjdk" class="mention hashtag" rel="nofollow noopener" target="_blank">#openjdk</a>

Peter TribbleRecently in the background I've been doing test build of some of my projects with newer jdk versions.I'm getting a shedload of lint warnings. We are talking old code (it doesn't seem that long ago I started targetting jdk8 rather than 5), but especially jdk21 is getting really grumpy. I can fix a lot of the complaints, but in some cases I can't see any alternative to simply turning the warning off.It's not just javac, javadoc is also getting more demanding.<a href="https://mastodon.social/tags/openjdk" class="mention hashtag" rel="nofollow noopener" target="_blank">#openjdk</a>
