Test and Documentation Plan

To test,

Either a clean checkout or remove the .idea directory, then under Java8 and Java11 run ant generate-idea-files then load the project and compile.

Under Java11, check Preferences -> Build, Execution, Deployment -> Java Compiler and there should be an entry under Additional command line parameters: you should see

--add-exports java.rmi/sun.rmi.registry=ALL-UNNAMED

Under Java8, no .idea/compiler.xml file should be generated.

Description

The change to JMX in CASSANDRA-15653 prevents the generated IDEA project from compiling under JDK11.

Fix by adding options for a module (named after the checkout dir)

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="JavacSettings">
    <option name="ADDITIONAL_OPTIONS_OVERRIDE">
      <module name="trunk" options="--add-exports java.rmi/sun.rmi.registry=ALL-UNNAMED" />
    </option>
  </component>
