Wildfly Undertow请求在Webservice上的HttpServerExchange失败

Question

我正在尝试访问运行在Wildfly实例上的Wildfly服务。webservice被注释为Post并接受JSON。当我尝试调用该服务时，我的Wildfly抛出了一个Nullpointerexception。

实际的堆栈跟踪如下所示：

15:23:40,324 ERROR [io.undertow.request] (default task-1) Undertow request  failed HttpServerExchange{ POST <path to my service>}: java.lang.NullPointerException

我真的不明白是什么引发了Nullpointerexception，因为我对Wildfly开发不是很熟悉。

这似乎是WildFly的缺陷：UNDERTOW-367: NullPointerException when POST method has no ordinary parameters
