title: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.misc)
body: <p>So my hosting company changed their service to tomcat 7 with security manager, and from that time on I am getting this exception every time my application tries to connect to MySQL database with Hibernate. I don't know what to do, they ask me for my Tomcat permissions, but I have not defined anything special.</p>
  
  <p>Can any one help me?</p>
  
  <p>This is my stack trace: </p>
