java - 本地代码深处的 FileDialog.open() 偶尔导致 JVM 崩溃

Question

我目前面临的是在 Windows 2008 服务器 R2 上的 Citrix 环境中运行的某些 Eclipse 应用程序中的异常访问冲突。

通话开始于org.eclipse.swt.widgets.FileDialog.open() ，调用 org.eclipse.swt.internal.win32.OS.GetSaveFileNameW 中的方法然后转到本地库。它失败了 # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x68931bab, pid=9208, tid=7616与 siginfo: ExceptionCode=0xc0000005, ExceptionInformation=0x00000008 0x68931bab

分析创建的小型转储，我以 thumbcache.dll 结尾

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

Answer 1

我找到了 this错误报告似乎与您所看到的非常相似。它被标记为不会修复，但是有一个解决方法建议:

I'm going to close this as "won't fix" which simply means that we aren't going to try to work around it in swt code.

I have also added the following item to the eclipse 3.3 release notes:

Opening File Dialog crashes eclipse (Vista only)On Vista, launching eclipse using -vmargs -Xmx[any size] can crash eclipse when the FileDialog is opened. The workaround is to use the default heap size, i.e. do not use the -Xmx VM args. See bug 188317 for details.

它说“仅限 Vista”，但在发布时，Windows Server 2008 R2 甚至还不存在，所以我至少会试一试...

此错误报告中的另一条评论指出:

My error only happens when I open a FileDialog with the shell from a PopupDialog.

你的程序是这样吗？
