[jira] [Commented] (CASSANDRA-18431) Cassandra doesn't start on JDK17
[ https://issues.apache.org/jira/browse/CASSANDRA-18431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17709106#comment-17709106 ]

-------------------------------------------------
[Patch|https://github.com/ekaterinadimitrova2/cassandra/commit/77b2a7a7d230a404339e1d7413e01d3664b8a9c3], [CI|https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra/2322/workflows/20db9d1b-90ee-44dc-9cd5-6360b5f9671d]
[~dcapwell], [~mck] - I believe this brought us to the CI run seen [here|https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra/2322/workflows/20db9d1b-90ee-44dc-9cd5-6360b5f9671d] before CASSANDRA-17199
We can revert when jamm gets upgraded in CASSANDRA-18329

> URL: https://issues.apache.org/jira/browse/CASSANDRA-18431

> Issue Type: Bug
> Components: Build
> Reporter: Ekaterina Dimitrova
> Assignee: Ekaterina Dimitrova
> Priority: Normal
> Fix For: 5.x

> CASSANDRA-17199 added a new call to jamm measureDeep which hits some JDK internals and prevents us from starting Cassandra with JDK17. This will be solved with CASSANDRA-18329.
> Until new version of jamm lands we can workaround the problem either by adding add-opens or by replacing temporarily
> {code:java}
> public static final long IPV6_SOCKET_ADDRESS_SIZE = ObjectSizes.measureDeep(new InetSocketAddress(getIpvAddress(16), 42));
> {code}
> with
> {code:java}
> public static final long IPV6_SOCKET_ADDRESS_SIZE = 168;
> {code}
> measured with JOL.
> Then we can switch back to the current call [here|https://github.com/apache/cassandra/commit/4444721b6de555352bf0ac3ef7e36f94dc832f41#diff-1122d7d3efe9721af7244d373e66378f7e90cb05fd65859a52e8a3ea58a7c8f9R45] later.
