Description

We're saying that C* has experimental JDK 17 support yet the 5.0 branch can't be built with it.  

 

ubuntu@ip-172-31-36-36:/usr/local/cassandra/current$ ant
Buildfile: /usr/local/cassandra/trunk/build.xml
     [echo] Non default JDK version used: 17
init:
BUILD FAILED
/usr/local/cassandra/trunk/build.xml:388: Directory /usr/local/cassandra/trunk/build/classes/main creation was not successful for an unknown reason
Total time: 1 second
ubuntu@ip-172-31-36-36:/usr/local/cassandra/current$ java -version
openjdk version "17.0.10" 2024-01-16
OpenJDK Runtime Environment (build 17.0.10+7-Ubuntu-122.04.1)
OpenJDK 64-Bit Server VM (build 17.0.10+7-Ubuntu-122.04.1, mixed mode, sharing)

Trying to use a similar flag to -Duse.jdk11=true fails as well:

 

ubuntu@ip-172-31-36-36:/usr/local/cassandra/current$ ant -Duse.jdk17=true
Buildfile: /usr/local/cassandra/trunk/build.xml
     [echo] Non default JDK version used: 17init:BUILD FAILED
/usr/local/cassandra/trunk/build.xml:388: Directory /usr/local/cassandra/trunk/build/classes/main creation was not successful for an unknown reasonTotal time: 0 seconds

I see this in build.xml:

<property name="java.supported" value="11,17" />

 

I think a bigger picture question is, why do we require special flags to build different JVM versions?  Is this a limitation of ant, or the way we've configured it?
