garbage-collection

I've often read that in the Sun JVM short-lived objects ("relatively new objects") can be garbage collected more efficiently than long-lived objects ("relatively old objects")

Why is that so?
Is that specific to the Sun JVM or does this result from a general garbage collection principle?
