My favorite terms from the old Sun JDK Supplemental License:
4. High Risk Activities. Notwithstanding Section 2, with respect to high risk activities, the following language shall apply: the Software is not designed or intended for use in on-line control of aircraft, air traffic, aircraft navigation or aircraft communications; or in the design, construction, operation or maintenance of any nuclear facility. Sun disclaims any express or implied warranty of fitness for such uses.
