I have a test with the following code:
ImageOutputStream ios =
   ImageIO.createImageOutputStream(new File(path + "temp." + format));
...
writer.setOutput(ios);
...
if (writer.canReplaceImageMetadata(0)) {
...

Here format is tif, and with this PIT for (supposedly) jdk9 b105 the test fails with java.lang.IllegalStateException: getOutput() == null!
thrown from javax.imageio.ImageWriter.canReplaceImageMetadata(0).
However setOutput with non-null argument was called. Between these two calls there was only a couple of getters invoked.

Looks like a bug introduced with a fix either to JDK-8145113 or JDK-8144991
