Hi,
Please review a simple fix in JDK9: Bug : https://bugs.openjdk.java.net/browse/JDK-8144744 Webrev : http://cr.openjdk.java.net/~jdv/8144744/webrev.00/ Issue : Specification of ImageWriter.replacePixels() mentions that Illegal argument exception will be thrown if argument param is null. Root cause : Implementation of repalcePixels() API is in TIFFImageWriter and we actually use default ImageWriteParam if incoming argument param is null and don't throw IllegalArgumentException. Solution : Remove the comment in 'Throws' clause of specification which mentions that IllegalArgumentException will be thrown if param is null. Thanks, Jay
