Anything that loads core classes via reflection or via its own class
loaders, as you must already know by now.

Aside from the technical reasons:

It's a different way of thinking about the world.  With free software,
we share libraries between applications.  That way, if a user of one
application finds a bug in a library, they report it and it gets
fixed, and all the other applications that link to the library get the
fix too.  By co-operating we all benefit.  By linking statically you
make sure that other users can't use the library code you have linked,
but you don't get their help either.

Protect it from what?  Alien invasion?  Herds of rampaging Wildebeest?  :-)
