**Issue Evaluation** Category: `bug` | Status: **Confirmed** This is a known JDK 17 compatibility issue. The `NoClassDefFoundError: Could not initialize class io.netty.util.internal.PlatformDependent0` occurs because older Netty versions use internal JDK APIs that were removed/restricted in JDK 17. **Root Cause:** The dashboard depends on a Netty version older than 4.1.77 that relies on `sun.misc.Unsafe` internal access patterns blocked by JDK 17 module system. **Fix:** Upgrade Netty to 4.1.82+ as suggested. This resolves the PlatformDependent0 initialization failure. **Note:** This issue has been open since Nov 2023 and marked stale. A PR upgrading the Netty dependency would be welcome. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
