title: Multiple Add-Opens in Java Jar MANIFEST
body: <p>I have an executable Jar which is using reflection in order to access some java internal (actually I am shading some third party library like Netty, DNSJava...)</p>
  
  <p>I see that adding this entry to the MANIFEST of the Jar </p>
  
  <pre><code>Add-Opens: java.base/sun.net.dns
  </code></pre>
  
  <p>solves my first problem:</p>
  
  <pre><code>WARNING: An illegal reflective access operation has occurred
  WARNING: Illegal reflective access by org.xbill.DNS.ResolverConfig (file:/home/diennea.lan/enrico.olivelli/dev/magnews/magnews.installer/target/magnews-24.05-SNAPSHOT.dev-b199bacf8f2-noci-installer.jar) to method sun.net.dns.ResolverConfiguration.open()
  WARNING: Please consider reporting this to the maintainers of org.xbill.DNS.ResolverConfig
  WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
  WARNING: All illegal access operations will be denied in a future release
  </code></pre>
  
  <p>But now I have a second warning:</p>
  
  <pre><code>WARNING: An illegal reflective access operation has occurred
  WARNING: Illegal reflective access by org.postgresql.jdbc.TimestampUtils (file:/home/diennea.lan/enrico.olivelli/dev/magnews/magnews.installer/target/example/.tmpPackage/packages/postgresql.jar) to field java.util.TimeZone.defaultTimeZone

  WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
  WARNING: All illegal access operations will be denied in a future release
  </code></pre>
  
  <p>And I need to add this new exception</p>
  
  <pre><code>Add-Opens: java.base/java.util
  </code></pre>
  
  <p>I am trying with:</p>
  
  <pre><code>Add-Opens: java.base/java.util,java.base/sun.net.dns
  Add-Opens: java.base/java.util;java.base/sun.net.dns
  Add-Opens: java.base/java.util:java.base/sun.net.dns
  </code></pre>
  
  <p>Without results.
  I can't find any "specification" about Add-Opens</p>
