The issue affects all jimage commands.

Tested on the latest jigsaw and jdk 9-ea+144.
Comments
False alarm, when running some test fail in different ways, but that appears to be an issue with the tests, e.g: tools/jimage/JImageExtractTest.jtr java.io.IOException: "./JImageExtractTest8307723459751109927not_an_image" is not an image file at java.base/jdk.internal.jimage.BasicImageReader.<init>(BasicImageReader.java:148)
