The API spec for jdk 1.5.0-b23 say for the class BMPImageWriteParam:
"By default, no compression is used (the compression type is "BI_RGB")".
But the methods getCompressionType() return 'null' as default value.

The example:
-------------------------- test.java ----------------------------
import java.io.PrintStream;
import javax.imageio.ImageWriteParam;
import javax.imageio.plugins.bmp.BMPImageWriteParam;

class test {

    public static void main(String argv[]) {
        BMPImageWriteParam biwp = new BMPImageWriteParam();
        if (setModeExpl(biwp) != 0) {
            System.out.println("Unexpected exception");
            return;
        }
        if(!"BI_RGB".equals(biwp.getCompressionType())) {
            System.out.println("FAILED. Incorrect default value for CompressionType: " +
biwp.getCompressionType());
            return;
        }
        System.out.println("OKAY");
    }

    private static int setModeExpl(BMPImageWriteParam biwp) {

        try {
            if (biwp.getCompressionMode() != ImageWriteParam.MODE_EXPLICIT) {
                biwp.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
            }
        } catch (RuntimeException re) {
            System.out.println("Unexpected exception: " + re);
            return -1;
        }
        return 0;
    }
}
