Mark Struberg commented on MYFACES-4225: ---------------------------------------- Probably just an oversight. Ofc for every negative cache which can be triggered by an external request should have a configurable max size. Otherwise it might be possible to create an OOM by just firing requests with a UUID for example ;) > [perf] Cache whether a library exists in ExternalContextResourceLoader > ---------------------------------------------------------------------- > > Key: MYFACES-4225 > URL: https://issues.apache.org/jira/browse/MYFACES-4225 > Project: MyFaces Core > Issue Type: Improvement > Affects Versions: 2.2.11 > Reporter: Christian Beikov > Priority: Major > > I'm seeing many {{sun.nio.fs.UnixException}} being thrown in the underlying > code because {{ExternalContextResourceLoader.libraryExists}} calls > {{ExternalContext.getResource}} which in the end checks if a file exists on > the FS. I'd suggest when the project stage is PRODUCTION, this should be > cached. Maybe this could be done by installing an {{ExternalContextWrapper}} > that caches all resource lookups? I just see that parsing a XHTML causes many > exceptions to be thrown internally which negatively affects performance. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
