Question

我使用SparkJava 2.3.0编写了一个使用Jetty 9.4.4.v20170414的简单代理。不幸的是，代理在Android 8（API 26）上运行良好，但它不适用于Android 7（API 24）。

我得到的线索是堆栈跟踪：

看起来Google在API 26中添加了一个符合Java 8的方法ThreadLocal<S> ThreadLocal.withInitial (Supplier<? extends S> supplier)（link），Jetty使用了这种方法。

有没有办法在26之前的Android API上使用SparkJava？或者使用以前版本的Jetty？我试图降级SparkJava，但它仍在使用相当新版本的Jetty。

在v26之前的API级别上的SparkJava
