This is not a concern for strangelets in cosmic rays, because they have had time to decay to their ground state, which is predicted by most (though not all) models to be positively charged, so they are electrostatically repelled by nuclei, and would rarely merge with them. However, high-energy collisions could produce negatively charged strangelet states that live long enough to interact with the nuclei of ordinary matter.
So when is the EU finally going to request fingerprints and private data from US travelers?
not only that, 1.4.2 is going out of maintenance very soon: http://java.sun.com/j2se/1.4.2/
