我们有一个应用程序，我们最近添加了JavaFX，并更新到最新的JRE，现在Jwrapper不会在Windows上启动应用程序（MacOS和Linux都很好）。
我们已按照此帖http://www.jwrapper.com/blog/bundling-javafx-into-a-native-exe上的说明操作，并相应更改了我们的JWrapper配置。
我们使用的是JDK1.80_102和JWrapper版本：jwrapper-00044250826.jar。我们正在通过maven构建（我们有一个插件可以执行此操作）。
应用程序下载，但不会启动。请参阅以下日志：

答案 0 :(得分：0)
注意：这是一种解决方法，而不是解决此问题的方法。
如果有其他人遇到此问题，则一个解决方法将使用 32位 Windows JRE。
正如在日志中可以注意到的那样，当JWrapper启动JNI启动时，它将尝试＆＃34;服务器＆＃34; JVM优先（...\bin\server\jvm.dll），存在于64位JRE中。
然后，由于某些原因失败（JWrapper没有提供任何有用的信息），JWrapper将尝试加载＆＃34;客户端＆＃34; JVM（...\bin\client\jvm.dll）。
＆＃34;客户＆＃34; JVM并不存在于64位JRE中（并且它已经存在很长时间了，不确定为什么JWrapper仍在尝试加载它）。
现在，如果您使用 32位版本，您应该会注意到日志中的更改：

现在情况已经倒转，＆＃34;服务器＆＃34;找不到JVM，＆＃34;客户端＆＃34;是（如预期的那样）。
JWrapper仍然无法加载它，但它仍然没有提供任何有用的信息来说明它无法加载。
现在的主要区别在于，即使JWrapper无法加载客户端JVM，它也会尝试使用传统的spawn，这在我的情况下运行良好。
