title: Wildfly 8.2.1 final failed to parse configuration
body: <p>I have a question on wildfly server. You can see this error in the top image link. I think this problem happens because of JVM but I couldn't fix it.</p>
  
  <p>My OS is <strong>ubuntu 14.04</strong> and I had installed <strong>jdk 1.7 and 1.8</strong>.</p>
  
  <p>I changed default jdk to 1.7 . But I have also tried with jdk 1.8 and it was not working.</p>
