"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.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
