偶尔的JVM在本机代码深处从FileDialog.open()崩溃

Question

我目前面临的是我们在Windows 2008服务器R2上的Citrix环境中运行的一些Eclipse应用程序中的异常访问冲突.

调用开始org.eclipse.swt.widgets.FileDialog.open(),调用方法org.eclipse.swt.internal.win32.OS.GetSaveFileNameW然后转到本机库.它失败,并# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x68931bab, pid=9208, tid=7616 与siginfo: ExceptionCode=0xc0000005, ExceptionInformation=0x00000008 0x68931bab

分析创建的minidump,我结束了 thumbcache.dll

麻烦的是,问题很少发生.我们目前无法不断重现这个问题.它不时发生.我目前的猜测是,thumbcache.dll尝试创建ThumbnailCache的实例,由于某种原因不允许这样做.但我在windows领域的知识非常有限.有谁知道这个问题可能来自哪里？

我发现这个错误报告似乎与你所看到的非常相似.它标记为无法修复,但有一个解决方法建议:

我将关闭这个"不会修复",这只是意味着我们不打算尝试在swt代码中解决它.

我还在eclipse 3.3发行说明中添加了以下项目:

打开文件对话框崩溃eclipse(仅限Vista)在Vista上,使用-vmargs -Xmx [任何大小]启动eclipse可能会在FileDialog打开时崩溃.解决方法是使用默认堆大小,即不要使用-Xmx VM args.有关详细信息,请参阅错误188317.

它说"只有Vista",但截至发布时,Windows Server 2008 R2甚至不存在,所以我至少试一试......

此错误报告中的另一条评论指出:

我的错误只发生在我从PopupDialog打开带有shell的FileDialog时.

你的程序就是这种情况吗？
