[Bug classpath/37128] New: Null pointer exception in BMPImageWriterSpi.canEncodeImage()

[mathieu dot baron at gmail dot com]

A Null pointer exception occurs in BMPImageWriterSpi.canEncodeImage() when the
writer instance is not assigned.

Current code:
    BMPInfoHeader ih = writerInstance.infoHeader;

Proposed solution: 
    call "getWriterInstance()" which will create a new instance of 
    the writer if not already created.

    Example:
        BMPInfoHeader ih = getWriterInstance().infoHeader;

How to Reproduce:
    // Read an image file
    BufferedImage bufferredImage = ImageIO.read(pInputFile);
    // Save it using Bitmap format: this will call
    // the method "BMPImageWriterSpi.canEncodeImage()" but the
    // WriterInstance will be null.
    boolean success = ImageIO.write(bufferredImage, 
        "Microsoft Windows BMP", pOutputfile);
