What classes were removed in Java 9?
On Java 8 my tool is working.
On Java 9 I get:
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/image/codec/jpeg/JPEGCodec
It seems that some classes have been removed.
I use the Oracle JDK on Windows.
The JDK 9 release note and The one for removed features.
They said
client-libs/2d Remove the com.sun.image.codec.jpeg package com.sun.image.codec.jpeg has been shipped as a non-standard API since JDK 1.2. It was always advertised as a stop-gap measure until a proper standard equivalent was provided. That replacement (javax.imageio) has been there since JDK 1.4. As a result JDK 9 finally removes the long deprecated com.sun.image.codec.jpeg API which has been flagged as intended for removal for several releases. Applications which still depend on it will need to be re-coded in order to run on JDK9. See JDK-8038838
