LWJGL glGenVertexArrays jvm crash

Hi guys - I hope you are able to help me with one of the nastiest bugs that I’ve seen so far :clue:
I’m using LWJGL and tried to implement VAO usage.
When I call glGenVertexArrays on some systems the whole jvm crashes. After some further investigation I got the following dump:

As far as I get it, the problem is that I try accessing some wrong storage memory (?)
But I don’t get what I’m doing wrong - after all I just call glGenVertexArrays …

Here’s the code of createMesh:

private void createMesh(float[] vertexCoords, float[] vertexTexCoords, float[] vertexNormalCoords) {

		vertexCount = vertexCoords.length / COORDS_PER_VERTEX;
		
		
		float[] combinedData = new float[vertexCoords.length+vertexNormalCoords.length+vertexNormalCoords.length];
		for(int i=0;i<vertexCoords.length; i++){
			combinedData[i] = vertexCoords[i];
		}
		for(int i=0;i<vertexTexCoords.length; i++){
			combinedData[i+vertexCoords.length] = vertexTexCoords[i];
		}
		for(int i=0;i<vertexNormalCoords.length; i++){
			combinedData[i+vertexCoords.length+vertexTexCoords.length] = vertexNormalCoords[i];
		}
		
		texOffset = vertexCount*3;
		normOffset = vertexCount*5;
		
		vao = glGenVertexArrays();
		
		glBindVertexArray(vao);
		vbo = glGenBuffers();
		glBindBuffer(GL_ARRAY_BUFFER, vbo);
		glBufferData(GL_ARRAY_BUFFER, createFloatBuffer(combinedData), GL_STATIC_DRAW);
		glEnableVertexAttribArray(0);
		glEnableVertexAttribArray(1);
				
		glVertexAttribPointer(0, COORDS_PER_VERTEX, GL_FLOAT, false, 0, 0);
		glVertexAttribPointer(1, TEX_COORDS_PER_VERTEX, GL_FLOAT, false, 0, texOffset*BYTES_PER_FLOAT);
		
		glBindVertexArray(0);
		
	}

I hope you can help since I’m really getting nowhere with this. Every feedback or clue is highly appreciated!
