URL: https://github.com/apache/rocketmq-dashboard/issues/187
应该需要升级netty如：
` <dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.1.82.Final</version>
</dependency>`

**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.
