Checkstyle before 8.18 loads external DTDs by default.

checkstyle was loading external DTDs by default, which is now disabled by default.

If needed it can be re-enabled by setting the system property checkstyle.enableExternalDtdLoad to true.

For Debian 8 'Jessie', this problem has been fixed in version 5.9-1+deb8u1.

We recommend that you upgrade your checkstyle packages.
