+# 2025-12-03 Meeting Notes
+
+## Agenda
+
+- Java 25 in SimRel, see https://github.com/eclipse-simrel/.github/issues/75
+- Follow-up: patching released Eclipse versions
+- Working group financial plan 2025
+
+## Minutes
+
+## Release 2025-12
+- Overall good shape
+- "Eierlegende Wollmilchsau" looks good
+
+## Follow-Up: Patching Released Eclipse Versions
+- Sebastian monitored respin of RC2, which is similar to what would need to be done
+- Sebastian talked with Hannes: everything should be in place for it
+- Question on whether to use this for fixing non-severe regression
+  - We should be careful to not pick every regression fix for providing a patch release
+  - But we could try out the process with a current regression
+
+## Working Group Financial Plan 2026
+- Working group's financial plan 2026 discussed last week at onsite meeting
+- Budget decreases and leads to reduction in possible funding of (release) engineering
+  - Other areas of investment are also decreased
+  - Planning council can do nothing about reduced budget but may have to deal with consequences
+- Question raised what to be cut first when budget is reduced
+  - Actual release engineering work does not necessarily decrease
+  - Only work directly funded by working group as shared effort of companies may decrease
+- Planning council will abstain from voting on financial plan due to the higher risk/difficulty it will put on fulfilling goals/duties by reduced budget for (release) engineering
+
+## Java 25 in SimRel
+- https://github.com/eclipse-simrel/.github/issues/75
+- SimRel requirements allow projects to move to next Java LTS 6-9 months after it release
+  - Will be either 2026-03 or 2026-06 for Java 25
+- Issue: no Temurin release for Windows on ARM (AArch64) yet
+  - TCK not passed
+  - Beta builds available that do not pass TCK are available
+  - Issue already exists for quite some time also with previous Java releases --> unclear when issue may be resolved
+  - We cannot ship a JDK build that does not pass TCK via JustJ/EPP
+- Other JDK 25 builds available for Windows on ARM
+  - https://learn.microsoft.com/en-us/java/openjdk/older-releases#openjdk-25
+  - https://www.oracle.com/java/technologies/downloads/#jdk21-windows
+- Options
+  - Drop support for Windows on ARM (e.g., in SWT and EPP products)
+  - Disallow moving to Java 25 for Eclipse 2026-03
+    - Eclipse Platform is only allowed to move to new LTS one release after SimRel
+	- Java 25 would be most interesting for Platform / SWT (due to FFM)
+	- Unclear what to do if situation is the same in 3 months
+- Proposal
+  - Do not allow SimRel participants to move to Java 25 for the Eclipse 2026-03 release
+  - Reevaluate the situation in February/March to see if Windows on ARM support needs to be dropped for 2026-06 or whether Java 25 will not be allowed for 2026-06 as well
+  - In case SimRel participants will be allowed to move to Java 25 for the 2026-06 release, the Platform (including SWT) will be as well
+  - The proposal will be posted in the according issue https://github.com/eclipse-simrel/.github/issues/75
+    - All planning council members are given the chance to veto on this until Tuesday, 9th December 2025
+    - In case there is not veto, the planning council (chair) sends the decision to the SimRel mailing list
+- Everyone is encouraged to reach out to people involved into Windows on ARM support for Java 25 to clarify if/how/when the issue will be resolved
+
+
+## Next Meeting
+
+Next meeting will be on January 7th, 2026.
