> I have a JNI dll loaded by a Java process running as a Windows service on Windows 2019 using prunsrv. The JNI library is built with VC14, and makes calls to getenv(), which is imported from ucrtbase.dll.
> This call to getenv does not pick up environment variables that are set on the service via //US//Service ++Environment "key=value". Commons Daemon is setting these environment variables using _wputenv(), which is imported from msvcrt.dll.
> I started a discussion on the mailing list regarding this. I have patch which dynamically loads ucrtbase.dll and calls its _wputenv method as well, if it is available.
> I'm happy to provide changes or further patches, and work on this issue, but feedback would be useful and very much appreciated.
