[BUG] warning log entries (stderr) from lucene on startup

Describe the bug

starting a fresh cluster leads to the following log entries:

{"type": "server", "timestamp": "2026-04-22T13:53:25,584+0000", "level": "WARN", "component": "stderr", "cluster.name": "test-opensearch", "node.name": "test-opensearch-0", "message": "Apr 22, 2026 1:53:25 PM org.apache.lucene.internal.vectorization.PanamaVectorizationProvider <init>" }
{"type": "server", "timestamp": "2026-04-22T13:53:25,585+0000", "level": "WARN", "component": "stderr", "cluster.name": "test-opensearch", "node.name": "test-opensearch-0", "message": "INFO: Java vector incubator API enabled; uses preferredBitSize=256; FMA enabled" }

note that these are written to stderr rather than going through any logging framework.

No response

To Reproduce

start a fresh cluster (i used the minimal distribution) and check the log

Expected behavior

no such WARN log entries which are not actual warnings (or at least do not state what would be wrong and are not actionable)

Additional Details

Plugins n/a

Screenshots n/a

Host/Environment (please complete the following information):

• OS: linux
• Version OpenSearch 3.6.0

Additional context they also seem to be coming from lucene rather than OpenSearch; nevertheless i'm reporting this here since you're more familiar with how you integrate lucene and whether/how this can/should be fixed downstream.
