Dawid Weiss updated LUCENE-4624:
--------------------------------
Description:
Alex Snaps informed me that there's a sizeof estimator in terracota --
http://svn.terracotta.org/svn/ehcache/trunk/ehcache/ehcache-core/src/main/java/net/sf/ehcache/pool/sizeof/
looks interesting, they have some VM-specific methods. Didn't look too deeply
though; if somebody has the time to check out the differences and maybe compare
the estimation differences it'd be nice.
There is also another tool by Aleksey Shipilev. It looks very good to me
(Aleksey has deep knowledge of JVM internals).
