Aleatory One factory fails for the operation "encode"-JPEG

Question

I've a very strange problem with JAI.write using JPEG, but is happening aleatory. Some times it works, some times I get the exception and some other times don't. What I've seen is that when I got first this error, then all the rest of the images throws it. I mean, I'm working OK and then I got the exception, from there, all the images, no matter that they were not trowing exceptions before, now they do, so I don't know what is happening. I'll post some code snippets and the full stack trace of the exception. Hope you can help me:
First, I have a class that is a JSP-Tag:
RenderedOp outputImage = JAI.create("fileload", imgFile.getAbsolutePath());
int widthSize = outputImage.getWidth();
int heightSize = outputImage.getHeight();
try{
    outputImage.dispose();                         
}catch(Exception e){}
outputImage = null;That's the first thing, now, the second, this is a Servlet that writes the image to the browser (GetImageServlet its name, which appears in the stack trace):
FileSeekableStream fss = new FileSeekableStream(file);
RenderedOp outputImage = JAI.create("stream", fss);
int widthSize = outputImage.getWidth();
int heightSize = outputImage.getHeight();
if ((outputImage.getWidth() > 0) && (outputImage.getHeight() > 0)) {
                    if ((isThumbnail) && ((outputImage.getWidth() > 60) || (outputImage.getHeight() > 60))) {
                         outputImage = ImageManagerJAI.thumbnail(outputImage, 60);
                    } else if (outputRotate != 0) {
                         outputImage = ImageManagerJAI.rotate(outputImage, outputRotate);
                    OutputStream os = resp.getOutputStream();
resp.setContentType("image/jpeg");
     ImageManagerJAI.writeResult(os, outputImage, "JPEG");
                    outputImage.dispose();
                    os.flush();
                    os.close();
outputImage = null;
imgFile = null;The code of ImageManagerJAI.writeResult, which is a method I use above:
public static void writeResult(OutputStream os, RenderedOp image, String type) throws IOException {
          if ("GIF".equals(type)) {
               GifEncoder encoder = new GifEncoder(image.getAsBufferedImage(), os);
               encoder.encode();
          } else {
               JAI.create("encode", image, os, type, null);
     }And the full exception trace is:
Error: One factory fails for the operation "encode"

Please help, I don't know what to do, I've weeks with this problem. Dukes available pleaseeee!

Hi
you can check if you get in the error logs an message like 'Could not load mediaLib accelerator wrapper classes. Continuing in pure Java mode.' may be the problem of JAI native accelerator
