是否有机会获得-splash:< image>是否适用于需要-XstartOnFirstThread的SWT应用程序?

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此处或此.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!
