ClassNotFoundException jdk.net.* in Wildfly

Question

My app just started blowing up on startup after upgrading to latest MongoDB drivers. Using Wildfly 19, JDK14, and I've confirmed that at compile time jdk.net.* are available. Clearly they're either not making it into the runtime environment or there is a security issue. My guess is that the module is being blocked, but I've not been able to figure out how to get access to it.

Log output:

Answer 1

Figured it out. In the Wildfly standalone.xml file add

<global-modules>
<module name="jdk.net" slot="main" />            
</global-modules>

inside of the block

Answer 2

Using Wildfly 10.1, JDK 8. Adding the following block to the file jboss-deployment-structure.xml inside the dependencies section solved the problem.

<system export="true">
   <paths>
      <path name="jdk/net"/>
   </paths>
</system>
