带有javafx挂起的Eclipse应用程序

我有一个Eclipse4应用程序，其中某些部分用JavaFx实现，其余部分用SWT实现。应用程序间歇性挂起，下面是应用程序在应用程序启动时挂起时jconsole.exe的堆栈

我使用的是Java8。

您也可以包含您的代码吗？代码太大，无法包含在这里。我看到这种情况时有发生。有时它在应用程序启动时挂起，而其他时候它挂在执行的中间（没有特定的动作导致它挂起）。堆栈跟踪每次挂起时看起来都完全相同。很难确定为什么只有堆栈跟踪挂起。这是在什么操作系统上的？Windows 7。我的问题是一个经常被调用的侦听器，它使所有资源陷入困境。移除它解决了这个问题。
