Costin:
Is there any way to find out how many objects are created in the JVM?
I remember seeing something similar on a pre-release version of MacOS X: it
sampled the number of objects of the different core classes that were
allocated at any moment.
Otherwise, how do you find out how many objects are allocated by the
container with each request?
Just curious.
Un saludo,
Alex.
