run jdeps on our jars to see how dependent we are on api that might go away in Java 9 ------------------------------------------------------------------------------------- Key: JBIDE-18654 URL: https://issues.jboss.org/browse/JBIDE-18654 Project: Tools (JBoss Tools) Issue Type: Task Components: build Reporter: Max Rydahl Andersen Java 9 JDK team have been pinging various teams to check if they got depedency on API that is scheduled to disappear in Java 9. There is a tool called jdeps that we can use to check for this using the -jdkinternals flag. https://wiki.openjdk.java.net/display/JDK8/Java+Dependency+Analysis+Tool The sooner the better we get this done as it is feedback to the Java 9 team. If we can we should try run it on *all* jars, even eclipse ones to see what will be affected - but first of all jboss tools plugins.
