> Please review this change to the implementation of the Windows-specific option
> UseOSErrorReporting, toward allowing crash reporting functions to be declared
> noreturn. VMError::report_and_die no longer conditionally returns if the
> Windows-only option UseOSErrorReporting is true.
>
> The Windows-only sections of report_and_die now call RaiseFailFastException
> (https://learn.microsoft.com/en-us/windows/win32/api/errhandlingapi/nf-errhandlingapi-raisefailfastexception),
> which immediately invokes WER (Windows Error Reporting) if it is enabled,
> without executing structured exception handler. If WER is not enabled, it
> just immediately terminates the program. Thus, we no longer return to walk up
> thestructured exception handler chain to pop out at the top as unhandled in
> order to invoke WER.
>
> This permits declaring report_and_die as [[noreturn]], once some functions
> from the os class are also so declared. Also adding that attribute as
> appropriate to other functions in the os class. This of course assumes
> the use of [[noreturn]] in HotSpot code is approved (JDK-8302124).
>
> There is a pre-existing bug that I'll be reporting separately. If
> UseOSErrorReporting and CreateCoredumpOnCrash are both true, we create an
> empty .mdmp file. We shouldn't create that file when UseOSErrorReporting.
>
> Testing:
> mach5 tier1-3
>
> Manual testing with the following, to verify desired behavior.
>
> -XX:ErrorHandlerTest=N
> 1: assertion failure
> 2: guarantee failure
> 14: SIGSEGV
> 15: divide by zero
> path/to/bin/java \
> -XX:+UnlockDiagnosticVMOptions \
> -XX:+ErrorLogSecondaryErrorDetails \
> -XX:+UseOSErrorReporting \
> -XX:ErrorHandlerTest=1 \
> TestDebug.java

> --- TestDebug.java ---
> import java.lang.String;
> public class TestDebug {
> static private volatile String dummy;
> public static void main(String[] args) throws Exception {
> while (true) {
> dummy = new String("foo bar");
> }

> }
> --- end TestDebug.java ---

> The state of WER can be examined and modified using Power Shell commands
> {Get,Enable,Disable}-WindowsErrorReporting.
>
> The state of reporting WER captured errors can be examined and modified using
> Control Panel > Security and Maintenance > Maintenance : Report Problems [on,off]
>
> With Report Problems off, reports are placed in
> c:\ProgramData\Microsoft\Windows\WER\ReportArchive
>
> I verified that executing the above test with WER enabled adds an entry in
> that directory, but not when it's disabled. Also nothing is added there when
> the test is run with -XX:-UseOSErrorReporting.
