How to free memory allocated by LWJGL

Question

My Java application with LWJGL allocates memory indefinitely until the application is dropped. Apparently this part of the code is causing the allocation of memory in looping. Is there a memory release missing? Tks for help.

public void renderMesh(GameObject object, Camera camera) {
    GL30.glBindVertexArray(object.getMesh().getVAO());
    GL30.glEnableVertexAttribArray(0);
    GL30.glEnableVertexAttribArray(1);
    GL30.glEnableVertexAttribArray(2);
    
    GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, object.getMesh().getIBO());
    
    shader.bind();
    shader.setUniform("model", Matrix4f.transform(object.getPosition(), object.getRotate(), object.getScale()));
    shader.setUniform("view", Matrix4f.view(camera.getPosition(), camera.getRotation()));
    shader.setUniform("projection", window.getProjectionMatrix());
    
    GL13.glActiveTexture(GL13.GL_TEXTURE0);
    GL13.glBindTexture(GL11.GL_TEXTURE_2D, object.getMesh().getMaterial(0).getTextureID());

    GL11.glDrawElements(GL11.GL_TRIANGLES, object.getMesh().getIndices().length, GL11.GL_UNSIGNED_INT, 0);
    
    shader.unbind();
    
    GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, 0);
        
    GL30.glDisableVertexAttribArray(0);
    GL30.glDisableVertexAttribArray(1);
    GL30.glDisableVertexAttribArray(2);
    GL30.glBindVertexArray(0);
}

In your code there is nothing explicitly freeable. But there are possibly two elements:

1. Are you sure to free resources and buffers used by meshes of your object?
2. And did you delete your shader program after use?
