I am trying to render vertices in bindless mode

I create each mesh and get their 64b vertex array pointer

https://github.com/elect86/NvGlSamples/blob/master/NvGlSamples/src/nvGlSamples/bindlessApp/util/Mesh.java#L80

Then, before the mesh.render() I set the attributes, enable it and its client state

https://github.com/elect86/NvGlSamples/blob/master/NvGlSamples/src/nvGlSamples/bindlessApp/util/Mesh.java#L115-140

and in the mesh.render() I set up the pointers to the vertices attributes

https://github.com/elect86/NvGlSamples/blob/master/NvGlSamples/src/nvGlSamples/bindlessApp/util/Mesh.java#L186-188

and then finally render

But I get this at the glDrawElements

Caused by: com.jogamp.opengl.GLException: element vertex_buffer_object must be bound to call this method
        at jogamp.opengl.gl4.GL4bcImpl.checkBufferObject(GL4bcImpl.java:39146)
        at jogamp.opengl.gl4.GL4bcImpl.checkElementVBOBound(GL4bcImpl.java:39197)
        at jogamp.opengl.gl4.GL4bcImpl.glDrawElements(GL4bcImpl.java:5440)
        at nvGlSamples.bindlessApp.util.Mesh.render(Mesh.java:223)

I guess (hope) this is a bug of jogl that doesnt take in account the bindless rendering and requires a vbo in anycase.. or?
