## AOB

(5 min. max; tech. Discussion should be highlighted to relevant people and rescheduled)

## Main Topic

Technical discussion focusing on [Java version 17 suupport in OMERO.server](https://github.com/ome/openmicroscopy/issues/6383)
- Feedback on process welcome
- Java programming language - LTS releases
- Core OME repos in Java. Require Java 8+, Some Java 11
- Users need JRE to run apps
- Devs need JDK - OpenJDK released 2007 by Sun Microsystems
- Now multiple JDK distributions
- JDK builds only get support for 6 months
- Other vendors ship their own OpenJKD releases with different EOL
- e.g. RedHat JDK 11 EOL Oct 2024
- Bio-Formats 6.12.0 added support for Java 17
- recently added support for Java 21
- OMERO server doesn't yet support Java 17 - reflection issue
- Strongly encapsulated - can't access protected/private Java API methods
- workaround: use --add-opens to JVM
- also need --add-exports to avoid IllegalAccessError
- This allows us to run OMERO.server on Java 17
- These options not supported for Java 8.
- Next steps:
- review dependencies etc to remove need for reflection
