Thread.currentThread（）.join（）。它将以某种方式保持线程运行，防止在出现任何本机lib错误时由于可执行逻辑的结束而停止执行
在做了很多实验或者说反复试验之后，我发现了这个
保持应用程序运行所需的其他东西，或者在处理流时本机代码中的一个错误都会杀死整个应用程序。我使用自定义渲染器示例的实际代码是打开一个jwt框架，使应用程序保持打开状态。我删除了它，因为我不需要显示任何东西。但是，现在我开始有问题了。运行中的线程/类没有其他工作了，任何源于本机库的错误都将中断连接（专家可能会在这里使用更好的术语），因此程序将关闭，作为回报，JNI将触发回调对象并进行垃圾收集
我使用的是Thread.currentThread（）.join（）但在创建实例后在类之外，因此对承载用于呈现/处理数据的回调的类没有任何影响
考虑到jwt框架可能在做什么，我将其删除并替换为Thread.currentThread（）.join（）在构造函数中，瞧，它开始工作得很好。我看不出有什么明显的错误，但是JVM转储日志中的Java帧在终结器中，因此可能有一些包装本机资源的内容正在被垃圾收集。我看不到你的所有代码，但请检查你是否让你的应用程序保持活动状态，也许可以添加一个线程。currentThread（）.join（），以确保你的应用程序不会退出。@caprica我让它保持活动状态，而这只会在自定义渲染器中发生，如果我使用MediaPlayer…会出现这样的错误并继续播放，但这不是我想要的。在代码部分，我只是从主应用程序类调用这个类，并附带Thread.currentThread.join（）；我不知道。您发布的代码基本上是这样的-如果您运行该类而不做任何更改，它是否适合您？我只是自己运行，没有任何问题。@caprica如果您使用正确的行话和相关概念编辑我的答案，我将非常感谢您。谢谢，我的代码运行顺利。这基本上是正确的，我在前面的评论中也提出了同样的建议。这并不总是显而易见的，但对于本机回调，您必须特别注意确保（vlcj）Java对象不会被垃圾收集。正如您所发现的，当将本机代码与Java混合时，本机代码中的任何错误都会终止JVM——这是预期的行为。
