[BUG] Wazuh-indexer service warnings: Terminally Deprecated method has been called about opensearch

[msfroh]

OpenSearch makes pretty extensive use of the Java security manager. See #1687 for some discussion.

My takeaways from that issue are:

1. It's not great that the JDK devs have decided to deprecate the JSM without anything to replace it. (It does provide defense-in-depth advantages.)
2. While those warnings get emitted (with no way to suppress them) starting with JDK 17 (or 18? I think 17, though), they're just warning that eventually the JSM will be removed.
3. The JSM has not been removed in JDK21, which is the current long-term support version. So, while those warnings are annoying, they're just noise. If/when there's a LTS version that doesn't include security manager (hopefully a few years out), we'll need to figure out what that means for OpenSearch. (Do we abandon defense in depth? I hope not.)

@bradleybaasRB Thanks for creating this issue, due to OpenSearch's dependency on the security manage we cannot directly address this issue and are closing this out.

• If/when #1687 has been addressed it will resolve such errors
