title: Looking for jar that defines javax.activity (no longer provided by java.corba module as per JEP 320)
body: <p>I have a follow-up question in connection to <a href="https://stackoverflow.com/questions/48204141/replacements-for-deprecated-jpms-modules-with-java-ee-apis">Replacements for deprecated JPMS modules with Java EE APIs</a>, in particular the replacement of the java.corba module and its javax.activity package.</p>
  
  <p>I am looking for a jar file that provides javax.activity.</p>
  
  <p>I see javax.rmi, javax.rmi.CORBA, and org.omg.* provided by glassfish-corba-omgapi-4.2.0-b004.jar, but I'm unable to locate a jar file that defines javax.activity. Is there any? </p>
  
  <p>I did find openjdk-orb-8.1.2.Final.jar providing it, but it get an error when I try to use it as an automatic module:</p>
  
  <pre><code>Error occurred during initialization of boot layer
  java.lang.module.FindException: Unable to derive module descriptor for /Users/jluehe/blt/app/main/core/sfdc/modules_jdk_11-ea_x64/modules/openjdk-orb-8.1.2.Final.jar
  Caused by: java.lang.NullPointerException
  </code></pre>
  
  <p>Any hints appreciated. Thanks!</p>
