Hi all,
It's been more than 2 month since I've created WICKET-2889 and submitted
a patch to fix it. As nobody commented yet, I thought I should mention
it here.
The attached patch reduced required heap space for stateful pages by 2/3
(depends on configuration though, >100M for my application running with
a total heap of 768M) without any noticeable impact on performance. I'm
using a custom PageMap that requires a few trivial changes in
SecondLevelCachePageMap (visibility and a hook called
onAfterLastPageSet(..)). I doubt that there's any reason not to apply it
for 1.4.10. Whether to include the new class
(ExpiringSecondLevelCacheSessionStore) is optional, but I'd consider it
a valuable addition to core.
Please see https://issues.apache.org/jira/browse/WICKET-2889
<https://issues.apache.org/jira/browse/WICKET-2361>
<https://issues.apache.org/jira/browse/WICKET-2361> for details.
Cheers, Stefan
