A similar symptom can be reproduced with FirstUnoContact DevGuide example. It
can be found here:

LibreOffice Developer's Guide: Chapter 1 - First Steps
https://wiki.documentfoundation.org/Documentation/DevGuide/First_Steps#First_Contact

Upon running it in official way, I get:

$ make FirstUnoContact.run
"/usr/bin/java" 
-Dcom.sun.star.lib.loader.unopath="/opt/libreoffice7.6/program" -jar
/home/hossein/libreoffice7.6_sdk/LINUXexample.out/class/FirstStepsExamples/FirstUnoContact.jar
warning: com.sun.star.lib.util.NativeLibraryLoader must be loaded by
com.sun.star.lib.unoloader.UnoClassLoader for java_uno bridge to work (not a
problem if this is using Java remote bridge or unit test)
Connected to a running office ...
remote ServiceManager is available

It is possible to run it manually:

You only need to copy FirstUnoContact.java somewhere, and then invoke:
(assuming LibreOffice 7.6 on Linux)

$ javac -cp /opt/libreoffice7.6/program/classes/unoil.jar FirstUnoContact.java
$ java -cp .:/opt/libreoffice7.6/program/classes/unoil.jar FirstUnoContact
warning: com.sun.star.lib.util.NativeLibraryLoader must be loaded by
com.sun.star.lib.unoloader.UnoClassLoader for java_uno bridge to work (not a
problem if this is using Java remote bridge or unit test)
Connected to a running office ...
remote ServiceManager is available

On Windows:

> javac -cp "c:\Program Files\LibreOffice\program\classes\unoil.jar" 
> FirstUnoContact.java
> java -cp ".;c:\Program Files\LibreOffice\program\classes\unoil.jar" 
> FirstUnoContact

com.sun.star.lib.unoloader.UnoClassLoader for java_uno bridge to work (not a
problem if this is using Java remote bridge or unit test)

remote ServiceManager is available

I tried using com.sun.star.lib.loader.Loader class, but it didn't help.

java -Dcom.sun.star.lib.loader.unopath="c:\Program Files\LibreOffice\program"
-cp ".;c:\Program Files\LibreOffice\program\classes\unoil.jar;c:\Program
Files\LibreOffice\program\classes\unoloader.jar;C:\Program
Files\LibreOffice\sdk\classes" com.sun.star.lib.loader.Loader FirstUnoContact

Having recently looked into this again, I'd like to add to my original
findings:

The problem only occurs when using a pipe connection. With a socket,
unoloader.jar isn't needed and no warning is printed. This might be a viable
workaround for some users.

Additionally, I tested versions 7.4.1 and 7.3.6 to verify that the problem
still occurs.

To make it work with Maven, the dependency on unoloader should be declared in
pom.libreoffice.xml, I think. Maybe something along those lines:


  

  org.libreoffice
  unoloader
  @version@

The libreoffice.jar META-INF/MANIFEST.MF contains

> Class-Path:  unoloader.jar ../

which should avoid the issue that code from libreoffice.jar can't find classes
from unoloader.jar?  But maybe that's how Maven works, which I have little idea
about.

At worst, we could revert the problematic

"ridljar: check that UnoClassLoader is used for NativeLibraryLoader" again. 
Michael, what do you think?

Stephan: just seeing "Java", "Uno", I think you might be interested in this one
:-)
