[jira] [Commented] (CASSANDRA-16895) Support Java 17
[ https://issues.apache.org/jira/browse/CASSANDRA-16895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17412148#comment-17412148 ]
Ekaterina Dimitrova commented on CASSANDRA-16895:
-------------------------------------------------
Some initial thoughts after some initial work done to remove Java 8 and add Java 17 for trunk:
-The Nashorn engine has been deprecated in JDK 11 as part of [JEP 335|https://openjdk.java.net/jeps/335] and and has been removed from JDK15 as part of [JEP 372|https://openjdk.java.net/jeps/372]. GraalVM can step in as a replacement for JavaScript code previously executed on the Nashorn engine. GraalVM provides all the features for JavaScript previously provided by Nashorn. Working on this part now.
-We will need more --add-exports and --add-opens as Java 17 is quite restrictive.
- Currently [this script |https://github.com/apache/cassandra/blob/trunk/build.xml#L147-L155]inclusion in build.xml leads to
_../cassandra/build.xml:147: Unable to create javax script engine for javascript,_ related to the Nashorn removal. My initial try to solve this didn't work. I left it for later as a lower priority task.
- ant updated; probably other dependencies will have to be updated too
