在ALPN和MSSQL驱动程序中使用Pushy抛出java.lang.IllegalAccessError

Question

我正在开发一个应用程序，它通过ALPN使用带有HTTP/2访问的Pushy来向苹果iPhones发送推送通知。

为此，我将JVM配置为根据请求使用ALPN，并使用以下VM参数。

-Xbootclasspath/p:<Path To ALPN JAR>

此连接到Apple Push Notification运行良好。

但是在同一个应用程序中，我有一个MSSQL通过MSSQL驱动程序连接到数据库。但是，当它试图连接到MSSQL时，它会引发以下错误：

java.lang.IllegalAccessError: tried to access field sun.security.ssl.Handshaker.algorithmConstraints from class sun.security.ssl.ClientHandshaker

有人能帮我做这件事或者给我指明正确的方向吗？

删除VM参数修复了Datasource问题，但ALPN连接失败。

更新

Jetty的ALPN-Boot库将覆盖包sun.security.ssl，这个包在jsse.jar中也是可用的(这意味着它是一个JVM核心类)，这会导致dataSource失败，因为MSSQL不是HTTP2服务器。

这就是为什么我

java.lang.IllegalAccessError: tried to access field sun.security.ssl.Handshaker.algorithmConstraints from class sun.security.ssl.ClientHandshaker

总之，我可以同时使用HTTP2和HTTP吗？
