[Bug]: Default start parameters not working for Solr 9.7.0

[der-eismann]

Module

Using the latest Testcontainers version?

Host OS

Linux

Host Arch

x86

Docker version

27.3.1

What happened?

I tried to run Solr 9.7.0 via the SolrContainer integration with solr.withZookeeper(true). However this failed to start, showing only the usage output:

Starting Solr

Usage: solr start [-f] [-c] [--host host] [-p port] [-d directory] [-z zkHost] [-m memory] [-e example] [-s solr.solr.home] [-t solr.data.home] [-a "additional-options"] [-V]
…
  --host <host>         Specify the hostname for this Solr instance

Turns out that Solr changed the format of start parameters to the commonly used --: https://issues.apache.org/jira/browse/SOLR-16824

Starting with -DzkRun --host localhost instead of -DzkRun -h localhost works great, so I thought of setting solr.setCommand("-DzkRun", "--host", "localhost"); to overwrite the args defined here, however this doesn't seem to work.

Would be great if Solr 9.7.0 could be used with embedded Zookeeper within testcontainers 🙂
