Running JAR from BAT file cannot find natives path-CodePudding

I am running my JAR from a BAT file on Windows 7 x64 machine. Lately I added native .dll files to project, so now I need to add the path to the BAT. My project is exported to "C:/dist" and folder with native libs called "natives" placed alongside, that is "C:/dist/natives".

The problem is that for some reason the path is ignored, or cannot be found, or it seems something else is wrong in the BAT. This is my BAT code:

@ECHO OFF
java -XX: UseG1GC -Xmx1G -server -Djava.library.path="C:/dist/natives" -jar data.jar
@if %errorlevel% neq 0 pause

When I run my project from the NetBeansIDE all works fine as expected. It is only when I try to run the compiled file from the BAT file it seems it cannot find the native libs when they are needed ending up with error.

I also tried add the path to the native libs programaticaly like this:

//PROGRAMATICALLY SET THE PATH TO NATIVE LIBRARIES
System.setProperty("java.library.path", "natives");
Field fieldSysPath = ClassLoader.class.getDeclaredField("sys_paths");
fieldSysPath.setAccessible(true);
fieldSysPath.set(null, null);

It works as it should in NetBeansIDE but not once the jar is compiled and run via BAT file.

This might have the same problem I mentioned at the beginning of this post of mine, namely one of these:

unnecessary jar files in your project (they might cause problems similar to yours)
mixing different versions of LWJGL jar files (might cause problems similar to yours)
mixing different versions of LWJGL native .dll files (might cause problems similar to yours)
using unneeded native .dll files (sometime unnecessary ones may cause errors like yours)
