Java 7使用Web Start打破OS X上的SWT应用程序
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：
由于我们已经升级到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？
问候，戈德。
这是webstart日志显示的内容：

我和Java 7一直在看这个，并且想知道它是否是基于另一个人的post的Java 7错误（我继续提交错误报告，因为我没有看到任何搜索Java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
