推荐答案

看起来像配置问题一样我的理解。有两种可能的原因/解决方案：

Seems like a configuration issue as per my understanding. There are two possible causes/solution to it:

1. 来自日志：

1. From the logs:

Root exception:
java.lang.ExceptionInInitializerError
    at com.jniwrapper.util.ProcessorInfo.b(SourceFile:95)
Caused by: com.jniwrapper.LibraryNotFoundException: Cannot find JNIWrapper native library (jniwrap64.dll) in java.library.path:

Eclipse无法正确配置 java.library.path ，在这种情况下你可以尝试使用命令行中的以下命令设置VM参数：

Eclipse is not able to configure the java.library.path properly, in which case you can try setting the VM argument using the following on the command line:

-Djava.library.path="${workspace_loc:project}\lib;${env_var:PATH}"

查看如何将本地库添加到java.library 。路径"使用Eclipse启动（而不是覆盖它）以获取更多详细信息和特定于平台的解决方案。

Check out How to add native library to "java.library.path" with Eclipse launch (instead of overriding it) for further details and platform specific solutions.

&& 确保包含jdk-9早期访问构建的路径，理想情况下该路径应该是基于Java9的插件所必需的。

&& make sure you include the path to jdk-9 early access build that should ideally be a must for the plugin used based out of Java9.

，日志读取

对于相关代码，您可能希望查看实现
GameField.java上的createGameField：217 。如果这在以前的java版本中没有特别发生，那么解决（1）应该摆脱这个，否则你可能想要在 Eclipse Bug：未处理的事件循环异常不再处理尝试。

For the pertaining code, you might want to look into the implementation of createGameField at GameField.java:217. If this wasn't specifically occurring on previous java version for you then solving (1) should get rid of this or else you might want to give the solutions at Eclipse Bug: Unhandled event loop exception No more handles a try.
