Mark Thomas commented on DAEMON-398:
------------------------------------

I was using Windows 7.

I think it would be useful to add a table to the issue description to track 
which combinations work and which do not. That should help us track down 
exactly where the problem lies. I'll get something set-up. Help populating it 
would be much appreciated. I'm not looking to populate all possible 
combinations - just enough to figure out where we should be looking for a root 
cause.

>                 Key: DAEMON-398
>                 URL: https://issues.apache.org/jira/browse/DAEMON-398
>             Project: Commons Daemon
>          Issue Type: Improvement
>          Components: Procrun
>    Affects Versions: 1.1.1
>         Environment: Windows
>            Reporter: Gerwin
>            Priority: Major
>         Attachments: set-stdout.patch

>
> *Steps to reproduce*
> # Install Java 11
> # Install prunsrv.exe using jvm.dll and specify stdout and stderr file.
> # Using prunmgr, add a Java Option '-invalid'
> # Start the service
> # stdout and stderr files are empty!
> # Install Java 10
> # Using prunmgr, switch the Java Virtual Machine to Java 10
> # Start the service
> # {code:none|title=stderr}
> Java HotSpot(TM) 64-Bit Server VM warning: Ignoring option MaxPermSize; 
> support was removed in 8.0
> Unrecognized option: -invalid
> {code}
> *Analysis*
> * It works for Java 8, 9 and 10, fails for 11, 12 and 13-ea.
> * I followed this guide: [Redirecting standard I/O from within a 
> program|https://jdebp.eu/FGA/redirecting-standard-io.html] (see 
> [^set-stdout.patch]), but it didn't help.
> * Even when I compile prunsrv with Visual Studio 2017 15.9 (linker 14.16) and 
> test with Java 13-ea, which is also compiled with the same version (hence 
> using the same C-runtime library) it does not work.
> * The guide ends with what the probably causing the issue:
> {quote}
> ... the one problem that remains with redirecting Win32 file handles:
> It doesn't affect anything in the program using a different C runtime library 
> (such as a third-party DLL, for example).
> {quote}
> * Setting registry value Log/LogJniMessages=1, which is using the 
> {{vfprintf}} option of the 
> [JNI_CreateJavaVM|https://docs.oracle.com/en/java/javase/11/docs/specs/jni/invocation.html#jni_createjavavm]
>  does not help. Maybe because is is added after the user-specified Java 
> Options?
> *Ideas*
> # Make {{vfprintf}} the first parameter
> Downside of {{vfprintf}} is that it is hard to distinct between stdout and 
> stderr. Maybe make a JNI call to {{System.out}} and {{System.err}} to be able 
> to recognize the {{*File}} pointer and map to stdout and stderr accordingly.
> And I think that {{javajni.c/apxJavaSetOut()}} should not be required.
> # Log a bug for OpenJDK and try to get it fixed.
