Working on modules extracted from lib/modules (just feeding Jadecy with modules directories instead of jars), with version 9-ea+110-2016-03-17-022235.javare.4664.nc, I found just that: ### jdk.net: jdk.net: jdk.net.module-info java.base: jdk.net.ExtendedSocketOptions jdk.net.NetworkPermission jdk.net.SocketFlow jdk.net.Sockets ### If adding jsr305 jar (3.0.1) in a pseudo-module directory, I got that more: ### javax.annotation: java.annotations.common: javax.annotation.Generated javax.annotation.PostConstruct javax.annotation.PreDestroy javax.annotation.Resource javax.annotation.Resources jsr305: javax.annotation.CheckForNull javax.annotation.CheckForSigned javax.annotation.CheckReturnValue javax.annotation.Detainted javax.annotation.MatchesPattern javax.annotation.Nonnegative javax.annotation.Nonnull javax.annotation.Nullable javax.annotation.OverridingMethodsMustInvokeSuper javax.annotation.ParametersAreNonnullByDefault javax.annotation.ParametersAreNullableByDefault javax.annotation.PropertyKey javax.annotation.RegEx javax.annotation.Signed javax.annotation.Syntax javax.annotation.Tainted javax.annotation.Untainted javax.annotation.WillClose javax.annotation.WillCloseWhenClosed javax.annotation.WillNotClose ### and with xml-apis (2.0.2), many more, so not showing classes: ### javax.xml.parsers: java.xml: xml_apis: javax.xml.transform: java.xml: xml_apis: javax.xml.transform.dom: java.xml: xml_apis: javax.xml.transform.sax: java.xml: xml_apis: javax.xml.transform.stream: java.xml: xml_apis: org.w3c.dom: java.xml: xml_apis: org.w3c.dom.css: xml_apis: jdk.xml.dom: org.w3c.dom.events: java.xml: xml_apis: org.w3c.dom.html: xml_apis: jdk.xml.dom: org.w3c.dom.ranges: java.xml: xml_apis: org.w3c.dom.stylesheets: xml_apis: jdk.xml.dom: org.w3c.dom.traversal: java.xml: xml_apis: org.w3c.dom.views: java.xml: xml_apis: org.xml.sax: java.xml: xml_apis: org.xml.sax.ext: java.xml: xml_apis: org.xml.sax.helpers: java.xml: xml_apis: ### -Jeff
