Java 7使用Web Start打破OS X上的SWT应用程序

2019-10-06 20:03:59  阅读：245  来源： 互联网

标签：java macos java-7 swt 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：

解决方法:

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帖子的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
