Cannot load DocumentFactory

[Đư_c Linman]

Hello,

We install Jira 8.17.1 on Centos Stream 8 with port 8989 and use HTTPS.

Sometimes, We can't connect to this and can't ping to that.

We also have that warning on the log:

WARNING: Cannot load DocumentFactory: com.atlassian.core.xml.InterningDocumentFactory
Security framework of XStream not explicitly initialized, using predefined black list on your own risk.

Can anybody help me?

Can't say I came across this and most search engines find Confluence/Bamboo related things. 

https://jira.atlassian.com/browse/JRASERVER-72669 this one points to affected 8.17, claiming that 8.18 contains a fix.

Couple more on the topic, but mostly haven't really found much except a potential JVM argument workaround.

Again, never had this error, so I don't know exactly where this is coming from, but I would probably try to install 8.20 (which is a long-term support release) and confirm if the problem goes away.

Do you need specifically 8.17.1? It's a bit odd version. If upgrading is not an option then maybe adding a JVM arg 'xstream.allowlist.enable' to workaround it could work - but it seems that it could break some 3rd party apps according to a few of those posts.
