java.io.IOException：流关闭 - 在 Tomcat 8 - JavaMelody - JAX WS

Question

我已将 Tomcat 从版本 7 升级到版本 8.0.30。在调用 WebService 方法之前一切正常，这应该 return 结果。

[Edit: 25.01.2016] 似乎响应是空的，连根标签都找不到。

当我切换回 Tomcat 7 时一切正常。我不知道在哪里寻找这些想法。你能帮我解决我的问题吗？

这是 javamelody PayloadNameRequestWrapper 的摘录

protected void initialize() throws IOException {
    //name on a best-effort basis
    name = null;
    requestType = null;

    final HttpServletRequest request = (HttpServletRequest) getRequest();
    final String contentType = request.getContentType();
    if (contentType == null) {
        //don't know how to handle this content type
        return;
    }

    if (!"POST".equalsIgnoreCase(request.getMethod())) {
        //no payload
        return;
    }

    //Try look for name in payload on a best-effort basis...
    try {
        if (contentType.startsWith("text/x-gwt-rpc")) {
            //parse GWT-RPC method name
            name = parseGwtRpcMethodName(getBufferedInputStream(), getCharacterEncoding());
            requestType = "GWT-RPC";
        } else if (contentType.startsWith("application/soap+xml") //SOAP 1.2
                || contentType.startsWith("text/xml") //SOAP 1.1
                && request.getHeader("SOAPAction") != null) {
            //parse SOAP method name
            name = parseSoapMethodName(getBufferedInputStream(), getCharacterEncoding());
            requestType = "SOAP";
        } else {
            //don't know how to name this request based on payload
            //(don't parse if text/xml for XML-RPC, because it is obsolete)
            name = null;
            requestType = null;
        }
    } catch (final Exception e) {
        LOG.debug("Error trying to parse payload content for request name", e);

        //best-effort - couldn't figure it out
        name = null;
        requestType = null;
    } finally {
        //reset stream so application is unaffected
        resetBufferedInputStream();
    }
}

protected BufferedInputStream getBufferedInputStream() throws IOException {
    if (bufferedInputStream == null) {
        //workaround Tomcat issue with form POSTs
        //see 
        final ServletRequest request = getRequest();
        request.getParameterMap();

        //buffer the payload so we can inspect it
        bufferedInputStream = new BufferedInputStream(request.getInputStream());
        // and mark to allow the stream to be reset
        bufferedInputStream.mark(Integer.MAX_VALUE);
    }
    return bufferedInputStream;
}


protected void resetBufferedInputStream() throws IOException {
    if (bufferedInputStream != null) {
        bufferedInputStream.reset(); // Exception happens here
    }
}

此问题与 AJP 连接器有关，不会出现在每个 tomcat 版本中。错误报告已经存在： https://bz.apache.org/bugzilla/show_bug.cgi?id=58481

在错误报告中，您可以找到一个 post，其中写着

Tomcat 7 应该可以工作到版本 7.0.59。错误出现在版本 7.0.61
Tomcat 8 应该可以工作到 8.0.20 版。错误出现在版本 8.0.21
