是否有机会获得-splash:< image>是否适用于需要-XstartOnFirstThread的SWT应用程序? [英] Is there a chance to get -splash:<image> work for SWT applications that require -XstartOnFirstThread?

问题描述

我正在使用以下命令启动Scala SWT应用程序:

I am launching my Scala SWT application using:

java -splash:splash.jpg -jar application.jar

在Mac OS X 10.9.1上使用JDK 1.6.0时，启动屏幕会立即打开(在打开实际应用程序窗口之前几秒钟).

Using JDK 1.6.0 on Mac OS X 10.9.1 the splash screen was opened immediately (seconds before the actual application window opened).

当SWT应用程序窗口打开时，我使用以下代码关闭了初始屏幕:

I used the following code to close the splash screen when the SWT application window opened:

// When the window opens for the first time close the splash screen if exists
val splash = SplashScreen.getSplashScreen
if (splash != null) {
  shell.addShellListener(new ShellAdapter {
    override def shellActivated(event: ShellEvent) {
      shell.removeShellListener(this)
      splash.close
    }
  })
}

行为符合预期: 当应用程序准备就绪时，我得到了一个很早的启动屏幕.

The behavior was as intended: I got a very early splash screen that was closed when the application was ready.

现在，在JDK 1.7.0_45上，在打开应用程序窗口并在splash.close处冻结应用程序时，启动屏幕已打开.

Now on JDK 1.7.0_45 the splash screen is opened the moment the application window was opened and the application freezes at splash.close.

我阅读了 https://www.java.net//node/668622 从Java 6到Java 7对SplashScreen API进行了一些更改，但这并不能解释完全不同的行为.

I read https://www.java.net//node/668622 that some changes were made to the SplashScreen API from Java 6 to Java 7 but that doesn't explain the totally different behavior.

在SWT应用程序的Java 7上运行JVM初始屏幕是否有变化?

Is there a change getting the JVM splash screen run on Java 7 for a SWT application?

仅供参考:我正在使用普通的SWT，但周围没有Eclipse(包括支持启动屏幕的Eclipse启动器).

FYI: I am using plain SWT without Eclipse (that includes the Eclipse launcher that supports splash screens) around it.

推荐答案

在JDK9或更高版本中也许会有解决方案.目前，在OS X Yosemite上使用JDK8时，此问题没有任何改善.

Maybe there will be a solution for this in JDK9 or later. At the moment with JDK8 on OS X Yosemite there is no improvement on this problem.

此刻，我将使用此摘录中的代码 rel ="nofollow">有.他们两个都在工作.

At the moment I'll use code from this snippet here or this one there. Both of them are working.

希望该错误将在JDK9中关闭！

Hopefully the bug will be closed in JDK9!
