That's 64 MB for the *Java heap*, not the entire process.  The process space 
includes lots of other things besides the Java heap, such as room for code, the 
C heap, other JVM structures, file maps, various bits of OS- and 
library-managed structures, etc.

Resident should always be <= virtual (unless your OS is very strange), and 
virtual will always be > Java heap.
