Texture Constructor always throws GLException

Im currently working on a basic game engine in java and im currently stuck on image loading, I want to do this with BufferedImages for consistancy with older versions of the engine (and backwards compability). I am using the TextureIO#newTexture(GL, TextureData) method for this, and I always  get this exception:

I already made out the reason, which is that it automatically assigns it the texID of 0,  but no way to change this/obtain a lvalid tex id. Is there any way to obtain a valid texID or do I have to keep track of them myself?

Please post a SSCCE. If we can't reproduce your bug, we won't be able to help you. A stack trace isn't enough.

There's a public Texture constructor that takes a texture identifier as first parameter, it should do the trick in your case but it's harder to use, don't forget to update the image.

Sorry for not attaching code, but soon after this post I found out why it didnt work and didnt think to update here, I basically just forgot to make my GLCanvas context current.

Be careful, there are plenty of ways to obtain bad performance. Several years ago, I found that Ardor3D was explicitly making contexts current whereas it wasn't necessary in some cases and our first attempt of using JOGL in JMonkeyEngine 2 managed the OpenGL context very badly. I advise you to look at the existing engines, see them as sources of inspiration.

Thank you very much for your advise.
