Tyler Hobbs commented on CASSANDRA-12074:
-----------------------------------------
Awesome, it looks like even with an older java 8 (1.8.0u20), the error message
is good:
{noformat}

So, I've pushed another commit to the branch that simply removes the
pre-startup check and started a new dtest run. Thanks to [~cnlwsu] for
mentioning CASSANDRA-10091 to me.
> Faster check for open JMX port on startup
> -----------------------------------------
>
> Key: CASSANDRA-12074
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12074
> Project: Cassandra
> Issue Type: Improvement
> Components: Lifecycle
> Reporter: Tyler Hobbs
> Assignee: Tyler Hobbs
> Priority: Minor
> Fix For: 3.x
>
>
> Since CASSANDRA-7254, we check whether the JMX port is available before
> starting Cassandra in order to provide a better error message when another
> Cassandra process is already running. The current check starts a Java
> process to do this, which takes ~3 seconds. Instead, we can use {{lsof}},
> which is basically instantaneous.
> By my estimate, this will shave about 40 minutes off our dtest runs.
