I see two different ways this applies.  One is that large applications 
typically assemble their own collections of jars instead of expecting 
them in the system classpath so they don't affect each others' updates 
(like using static libs for everything).  The other is that java 
developers seem to buy into writing unit tests and doing full regression 
testing before releases more than anyone else (my impression anyway...). 
  Maybe it is because development is so cumbersome already that adding 
testing overhead doesn't make that much difference - or they've had to 
automate it with something like Hudson.
