title: "Unrecognized option: --add-opens" Hyperledger Besu
body: <p>I want to get started with Hyperledger Besu, after following the steps of the <a href="https://besu.hyperledger.org/en/stable/HowTo/Get-Started/Starting-node/" rel="nofollow noreferrer">official documentation here</a> and running the following command:</p>
  
  <p><code>bin\besu --help</code></p>
  
  <p>I get the following error:</p>
  
  <pre><code>C:\Users\user\Desktop\besu-1.3.9&gt;bin\besu --help
  Unrecognized option: --add-opens
  Error: Could not create the Java Virtual Machine.
  Error: A fatal exception has occurred. Program will exit.
  </code></pre>
  
  <p>I get the same thing when running <code>bin\besu</code> or <code>bin\besu -help</code>.</p>
  
  <p>I don't know if the problem is with java's installation or with hyperledger besu trying to run unvalid/unrecognised option <code>bin\besu --add-opens</code>. I tried uninstalling then reinstalling java but this did not solve the issue, here is java's version:</p>
  
  <pre><code>C:\Users\user&gt;java -version
  Picked up _JAVA_OPTIONS: -Xmx512m
  java version "1.8.0_241"
  Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
  Java HotSpot(TM) Client VM (build 25.241-b07, mixed mode)
  </code></pre>
  
  <p>Any help would be appreciated!</p>
