Java 7使用Web Start打破OS X上的SWT应用程序

标签： java macos swt java-7 java-web-start

我们有一个通过使用SWT库的webstart启动的应用程序。

众所周知，osx需要swt库在主线程中运行，所以我们在jnlp中有这个：

<resources os="Mac"> 
    <j2se version="1.6+" java-vm-args="-XstartOnFirstThread"/>
    <jar href="swt-mac64.jar"/>
</resources>

由于我们已升级到Java 7（1.7.0_10），似乎webstart没有将“-XstartOnFirstThread”传递给它启动的java进程。

我可以从'ps'看到java进程没有得到“-XstartOnFirstThread”选项。

有谁知道如何让webstart回到之前的行为？

这是webstart日志显示的内容：

答案 0 :(得分：1)

我已经在Java 7中看到了这一点，并且想知道它是否是基于另一个人发布的这篇文章的Java 7错误（我继续并提交了一个错误报告，因为我没有看到任何来自Java的搜索错误数据库）：http://www.java.net/forum/topic/jdk/java-se/webstart-os-x-xstartonfirstthread

我发现的解决方法只是使用Apple提供的Java 6中的javaws，尽管我必须从命令行启动它： /System/Library/Java/Support/Deploy.bundle/Contents/MacOS/javaws myjnlp.jnlp
