GAE Java 8運行時：java.nio.file.InvalidPathException：請求URL中索引68處的非法char <：>

Question

我將Spring MVC（不是Spring Boot）用於基於Google App Engine REST的網絡應用程序。 今天，我將GAE Java運行時升級到1.8 （Java 8）和servlet-api 3.1。 AppEngine SDK 1.9.56版。

所有的彈簧豆都完美裝載，沒有任何錯誤。 我在處理請求時收到此異常：

這是我的appengine-web.xml：

<?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>

當我在GAE中使用Java 7運行時時，我沒有遇到這個問題。 請幫忙。

您似乎遇到了一個會影響Windows上的開發應用服務器的錯誤（它不會影響部署到生產App Engine的應用）。 該錯誤已在此處跟蹤： https : //issuetracker.google.com/issues/63595917

即將發布的SDK版本1.9.58中包含對此的修復程序。
