I merged two methods and leave it here in the "common" code. src/java.desktop/share/classes/com/sun/imageio/plugins/jpeg/JPEG.java line 205: > 203: * of the CMM class until someone actually needs it. > 204: * (e.g. do not init CMM on the request for jpeg mime types) > 205: */ It is not necessary to delay the usage of ColorSpace, it itself defers the usage of cmm. ------------- PR: https://git.openjdk.java.net/jdk/pull/3140
