title: what does changeit really do in java net ssl keystore?
body: <p>I saw the config like this below, the <code>changeit</code> really a password? or it will look for some encypted password file? Or it has special meaning to the keystore/truststore?</p>
  
  <pre><code>-Djavax.net.ssl.trustStore=as-install/domains/domain1/config/cacerts.jks 
  -Djavax.net.ssl.keyStore=as-install/domains/domain1/config/keystore.jks
  -Djavax.net.ssl.trustStorePassword=changeit
  -Djavax.net.ssl.keyStorePassword=changeit
  </code></pre>
  
  <p>I knew it is default password for java cacert, but is there any other meaning?</p>
