Description Petr Nejedly 2004-11-15 11:13:01 UTC

ValuesObjects seems to be related to structure
(type) of given MDR instance. Because about all of
the MDR instances in the IDE are of the same type
(org-netbeans-java, v0.61), all the ValuesObject
instances look the same. They contain the same
instances of values (typically constant Strings),
but for each such a value, there is private
instance of HashMap$Entry, instance of Integer and
space needed in containers.

I have compared two such ValuesObject instances
and they had exactly same content except element
#13, which was a nested ArrayList. But the nested
ArrayList had exactly the same content again, so
both the list and map values of all ValuesObject
instances in the IDE are equals().
They waste ~7KB of heap per classpath root, which
is ~2MB for my big scenario of nbbuild/misc.

I think all of these issues are going to be closed, aren't they?

Comment 2 Jaroslav Tulach 2009-05-15 12:05:40 UTC

Performance team no longer cares about mdr.

Comment 3 David Strupl 2010-09-23 09:14:20 UTC

I am closing all reports in category Java/Unsupported as wontfix. These should
be dead issues --- if the reported cases are against some live part of the
NetBeans IDE please reopen and we can discuss to which category they belong.
