Hi, http://openjdk.java.net/jeps/220 clearly states this:
"For tools that support the development of code for JDK 9 but which themselves run on JDK 8, a copy of this filesystem provider suitable for use on JDK 8 will be placed in the root directory of JDK 9 run-time images, in a file named |jrt-fs.jar|." jrt-fs.jar in jdk9 is not meant to be used with jdk 7. You've to migrate your tool/application to JDK 8 to use jrt provider from JDK 9. -Sundar On 12/5/2016 9:39 AM, Ess Kay wrote: > I am working on a utility currently running on Java 7 which will need to be > able process Java 9 classes and read the Java 9 bootstrap class bytecode > (e.g. java.lang.Object). > > Is there a stable, "official" way to read the Java 9 bytecode from Java 7 > where there is no "jrt" provider?
