I followed your advise so I commented the call to my class and I add all natives jar as dependencies to my plugin. They re in my bundle_pool folder, same level as jogl and gluegen jar.

Here s the error :
java.lang.UnsatisfiedLinkError: Can't load library: C:\FPP\eclipse\natives\windows-amd64\\gluegen-rt.dll

I don't even know from where it finds this path. (FYI "C:\FPP\eclipse" is my eclipse installation folder and there isn't a "natives" folder)

I'm actually running on a 64-bit JVM.
About the custom loader, may be I used a wrong term. I mean, because I develop an eclipse plugin, jogl can t find the requested nat libs (I don't know why but the automated loading doesn't work) so I have to copy them from my plugin to a tmp folder and set the path to this tmp folder in java.library.path
This happend at the very begining of my plugin life-cycle

That is what my class do. Thereafter I let jogamp loads nat libraries whenever it wants.
About the nat libs themselves, I put them (good os, arch and jogl version) in my bundle so I'm sure my class exposes good ones.

In addition i noticed that, when i use my class for expose nat libs as I said I have the UnsatisfiedLinkError: jogamp.nativewindow.jawt.JAWTFactory.JAWT_GetAWT1(Ljava/nio/ByteBuffer;)Z, but when i searching for nat libs that were loaded i could see that gluegen-rt and nativewindow_awt were succefully loaded PLUS awt.dll and jawt.dll

Is this normal ?

Odd things too, when i recall the jogamp part, so gluegen-rt and nativewindow_awt are load, I have an other error :
