Yes, Java handles fairly large numbers of objects quite well.
I program in Java at IBM, on the "San Francisco" project.
ibm.com
I wrote the collection code (Maps, Sets, Lists).
In our performance testing, we create collections having
100,000 elements (ie, a List of 100,000 Customer objects,
or a Set of 100,000 Warehouse objects). They aren't all in
memory at once (they are persistent, sitting in a db) but
the data structures are huge, and the total number of objects
active in the TPCC benchmark application is huge.
FYI, this was on a server w/ 512 Meg of RAM.
Actually, using smaller objects, a test program of mine has
created tens of thousands of Java objects, inserting and
manipulating them in my collection code (on my PC, 64 Meg).
I read about ZAW last Friday, and am skeptical - MS generally
talks real big... we'll see. Some of my IBM-earned $$ will
go into SUNW soon.
