GAE Java 8运行时间：java.nio.file.InvalidPathException：非法字符<:>位于索引68中的请求URL

Question

我对基于Google App Engine REST的web-app使用Spring MVC（不是Spring Boot）。今天我upgraded GAE Java runtime to 1.8（Java 8）和servlet-api 3.1。 AppEngine SDK版本1.9.56。

所有的春豆装载完美没有任何错误。我得到的，而其服务的请求此异常：

GET http://localhost:9080/api/systems/urn:bnb:system:0ee64dc1-5dcd-46a5-aeaa-3d15858cb79e/details

，这里是我的AppEngine-web.xml中：

<?xml version="1.0" encoding="utf-8"?> 
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0"> 

    <!-- Test GAE instance --> 
    <application>webapp-1013</application> 
    <version>1-2</version> 
    <threadsafe>false</threadsafe> 

    <runtime>java8</runtime> 

    <system-properties> 
     <property name="DEFAULT_ENCODING" value="UTF-8" /> 
     <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/> 
    </system-properties> 

    <sessions-enabled>true</sessions-enabled> 

    <inbound-services> 
     <service>warmup</service> 
    </inbound-services> 

</appengine-web-app> 

我没面子，当我使用Java 7运行与GAE这个问题。请帮忙。

看起来您正在碰到影响Windows上开发应用程序服务器的错误（它不影响部署到生产App Engine的应用程序）。我们正在跟踪此错误：https://issuetracker.google.com/issues/63595917

即将发布的SDK版本1.9.58中包含此问题的修复程序。
