这取决于编译器环境。 GCC不捕获这些。 Visual Studio和我之前用的Borland。

因此，关于崩溃的结论是，它取决于开发环境的质量。

c++ 规范说catch(…)必须捕获任何异常，但它不是在所有情况下都捕获。

至少我是这么想的。

Can you run your JNI-using Java application from a console window (launch it from a java command line) to see if there is any report of what may have been detected before the JVM was crashed. When running directly as a Java window application, you may be missing messages that would appear if you ran from a console window instead. Secondly, can you stub your JNI DLL implementation to show that methods in your DLL are being entered from JNI, you are returning properly, etc? Just in case the problem is with an incorrect use of one of the JNI-interface methods from the C++ code, have you verified that some simple JNI examples compile and work with your setup? I'm thinking in particular of using the JNI-interface methods for converting parameters to native C++ formats and turning function results into Java types. It is useful to stub those to make sure that the data conversions are working and you are not going haywire in the COM-like calls into the JNI interface. There are other things to check, but it is hard to suggest any without knowing more about what your native Java methods are and what the JNI implementation of them is trying to do. It is not clear that catching an exception from the C++ code level is related to your problem. (You can use the JNI interface to rethrow the exception as a Java one, but it is not clear from what you provide that this is going to help.)

让我在这里提一下:Java

try 
{
...
}
catch (Exception e)
{
...
}

可能无法捕获所有异常!其实我以前也遇到过这种事，很让人抓狂;Exception派生自Throwable。因此，从字面上看，要捕获所有东西，你不希望捕获异常;你想抓住Throwable。

我知道这听起来很挑剔，但是当你花了好几天时间试图弄清楚“未捕获的异常”来自于被try包围的代码时……catch (Exception e)" block来自哪里，它会一直跟着你。

通用的异常捕获机制 会非常有用。

表示怀疑。你已经知道你的代码坏了，因为它崩溃了。进食异常可能会掩盖这一点，但这可能只会导致更糟糕、更微妙的错误。

你真正需要的是一个调试器……

如果你正在寻找特定于windows的解决方案，那么有结构化异常处理: https://learn.microsoft.com/en-us/cpp/cpp/try-except-statement

代码如下所示

__try
{
   // code here may throw or make access violation
}
__except( EXCEPTION_EXECUTE_HANDLER )
{
    // after exception code here, e.g. log the error
}

它不仅可以捕获c++异常，还可以捕获访问违规或其他系统异常。
