+
+The goal of this project is to improve OpenJDK support for FreeBSD/amd64 and FreeBSD/arm64.
+
+Java is an important runtime environment for many high performance, critical enterprise systems.
+Making sure Java based applications run correctly and efficiently on FreeBSD is important to ensure that FreeBSD will continue to be a viable and attractive platform for enterprises, as well as businesses and organizations of all sizes.
+
+This quarter has been spent mostly on getting the upstreaming process properly going.
+We submit patches to a link:https://github.com/openjdk/bsd-port[separate repository] under the OpenJDK org on Github, and make sure that each PR is reviewed by at least one upstream reviewer.
+This way, when we get to the point where we want to merge our port into the upstream mainline, all commits should already be reviewed by someone in the project.
+
+This is a fairly slow process, as we depend on upstream reviewers having time.
+We also encounter that some of the changes that has been living in our port for a long time is rejected.
+Then we have to rework them, or if not strictly needed, just throw them out.
+I feel this is a useful correction, but sometimes causes quite a bit of work.
+
+
+In this quarter the following issues/milestones were reached:
+
+* OpenJDK 25 port was updated to link:https://reviews.freebsd.org/D56522[version 25.0.3].
+* Upstream mainline changes and bugfixes:
+  - link:https://github.com/openjdk/jdk/pull/30853[8382614: Consolidate implementation of current_stack_base_and_size on BSD]
