No suitable native library found. native.libpath.* vs java.library.path

Question

I encounter "No suitable native library found" when running some library (HDF5).

Full trace is follows:

As you see, library is called from inside HDF5 java library.

Java library is attached as bunch of jars in global libraries:

As you see, native library is included.

The question is whether this setting is sufficient? May be I require to add some directories to the PATH variable?

UPDATE

I found, that HDF5 code expects library inside native.libpath.jhdf5 , the code is from ch.systemsx.cisd.base.utilities.NativeLibraryUtilities#loadNativeLibrary() :

public static boolean loadNativeLibrary(String libraryName) {
      String linkLibNameOrNull = System.getProperty("native.libpath." + libraryName);
      if(linkLibNameOrNull != null) {
         return loadLib(linkLibNameOrNull);
      } else {
         String linkLibPathOrNull = System.getProperty("native.libpath");
         if(linkLibPathOrNull != null) {
            linkLibNameOrNull = getLibPath(linkLibPathOrNull, libraryName);
            return loadLib(linkLibNameOrNull);
         } else {
            linkLibNameOrNull = tryCopyNativeLibraryToTempFile(libraryName);
            return linkLibNameOrNull != null?loadLib(linkLibNameOrNull):loadSystemLibrary(libraryName);
         }
      }
   }

While IntelliJ sets java.library.path :

   public static void main(String[] args) {

      System.out.println("native.libpath.jhdf5 = " + System.getProperty("native.libpath.jhdf5") );
      System.out.println("java.library.path = " + System.getProperty("java.library.path") );

prints:

native.libpath.jhdf5 = null
java.library.path = D:\Users\Dims\Design\!Lib\sis-jhdf5-SNAPSHOT-r32355\sis-jhdf5\lib\nativejar\hdf5-windows-intel.jar

Why?

You may have the same problem as me. The problem was that i had include the jar for the 3 differents platforms (linux, windows and macOS) thus there was a conflict and this problem happen

If it does not solved the case (as it has do in mine) i suggest to consult the jhdf5 faq https://wiki-bsse.ethz.ch/display/JHDF5/JHDF5+FAQ
