Java 11 support: JDeps

[iluwatar]

This task is part of the Java 11 transition plan https://github.com/iluwatar/java-design-patterns/wiki/16.-Java-11-Transition

There’s a tool, JDeps, that’s part of the JDK 11 that you can run with a flag of -jdkinternals to check to see if a set of classes is using something it shouldn’t. Run JDeps on the project and its dependencies (see https://blog.codefx.org/tools/jdeps-tutorial-analyze-java-project-dependencies/) and report findings under this issue.

E.g. /usr/lib/jvm/java-11-openjdk-amd64/bin/jdeps -jdkinternals async-method-invocation/target/async-method-invocation-1.22.0-SNAPSHOT.jar

[iluwatar]

Get the list of jars to be inspected
find -name "*-1.22.0-SNAPSHOT.jar" > list.txt

Check the jars with the following scritpt

#!/bin/bash

set -x

cat list.txt | while read line
do
   /usr/lib/jvm/java-11-openjdk-amd64/bin/jdeps -jdkinternals "${line}"
