Now that Java is free again (from Oracle, starting with version 17), what is the status of support for Java 17?
We are stuck on XWiki 13 right now, as we are on Java 8. We looked into moving to OpenJDK, but we have issues with getting that done and are going to move to Java 17 instead. Will XWiki 13 or 14 work on Java 17? Has anyone tested this?
AFAIK XWiki is generally working well on Java 17 except for one problem with Velocity which root cause is [VELOCITY-952] Velocity is calling the "wrong" method - ASF JIRA (in short Velocity calls the “wrong” method from JVM point of view).
I do hope to find time to propose a pull request before the end of the 14 cycle if nobody else from Velocity feel the need to work on that.
Hi. To know the java support level please check Java Support Strategy - XWiki You’ll find there what we need to fix before we can consider that we support java 17 properly. Thx
EDIT: all the issues currently listed there are solved by starting XWiki with some JVM parameters except for [XWIKI-19229] Errors in Search Date filtering facets when running XWiki on JAVA 17 - XWiki.org JIRA which is related to https://issues.apache.org/jira/browse/VELOCITY-952 as Thomas mentioned.
