java.lang.NoClassDefFoundError: io/javalin/websocket/WsContext

[HeDaas-Code]

• 错误类型：java.lang.NoClassDefFoundError: io/javalin/websocket/WsContext
• 问题Mod：create_web_board-1.21.1-0.1.0.jar
• 根本原因：该mod试图使用Javalin库的WebSocket功能，但找不到必需的类 io.javalin.websocket.WsContext

从堆栈跟踪可以看出：

at TRANSFORMER/create_web_board@0.1.0/com.example.webboard.content.lifecycle.ServerLifecycle.onServerStarted(ServerLifecycle.java:51)

create_web_board mod在服务器启动时尝试初始化WebSocket功能，但由于缺少Javalin库的依赖而失败。

Fixed in 4dc210e. Released as v0.1.1. Download: https://github.com/HeDaas-Code/create_web_board/releases/tag/v0.1.1

Root cause: implementation("io.javalin:javalin:6.3.0") is dev-time only in moddev — runtime jar had no Javalin classes, hence NoClassDefFoundError.

Fix: wrap Javalin + every Jetty transitive in jarJar(implementation(...)) (moddev jarJar is root-only, transitive is NOT auto-embedded). 16 jarJar entries now in META-INF/jarjar/.

Regression guard: 3 new tests in JarContentsTest (file-present + classloader-resolve). 23/23 tests pass.
