/**
 * Java2SecTest demostrates the usages of AccessController class and Policy file(s) while Security Manager is enabled:
 * 1. testNoPrivilegePassed shows the usage of no AccessController but it still work fine
 * because it has all the permissions.
 * 2. testNoPrivilegeFailure shows the usage of AccessController with LessPermission.java,
 * which is not right approach.
 * 3. testDoPrivilegePassed shows the correct practice of java 2 security by granting the appropriate
 * permission in the policy file(s0 and wrapping the AccessController calls with MorePermission.java.
 * 4. testDoPrivilegeFailure shows the reverse call order of MorePermission and LessPermission
 * from testDoPrivilegedPassed.
 * 5. testAccessControlContextFailure shows the AccessContext which contains a no-permission class
 * on the stack can cause a failure. In our case, the no-permission class is
 * LessPermissionAccessControlContext.
