Build fails due to dangling comment

[matteo-gsr]

Hey Mo,

Seems like the build fails due to that dangling comment in the cluster tool. Can you perhaps avoid building aeron-all and only build the aeron-archive, aeron-client, aeron-media-driver targets?

By the way, this is only happening if you are on the latest jdk (23).

Seems to be getting called by cmake files from aeron. I think the change will need to be done on the aeron side

[matteo-gsr]

see aeron-io/aeron#1710

@mimran1980 - can you update aeron? They fix is in upstream now.

[mimran1980]

@matteo-gsr Thanks for raising that. If you use 0.1.55 that should now work resolve the issue. I updated the ci to also use jdk 23 to confirm it works.
