[Guy Levkowitz]

Hey

when i run below command we get:
 java -jar gerrit3.12.2.war init -d . --batch --delete-caches --install-all-plugins --no-auto-start
WARNING: A restricted method in java.lang.foreign.Linker has been called
WARNING: java.lang.foreign.Linker::downcallHandle has been called by the unnamed module
WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for this module

Sep 28, 2025 1:32:17 PM org.apache.lucene.internal.vectorization.VectorizationProvider lookup
WARNING: Java vector incubator module is not readable. For optimal vector performance, pass '--add-modules jdk.incubator.vector' to enable Vector API.

Is this Ok ?

This Java warning is raised for lucene which has some optional implementation using Java vector APIs which are still in incubation in JDK 25

See e.g. https://github.com/apache/lucene/blob/releases/lucene/10.2.2/lucene/core/src/java21/org/apache/lucene/internal/vectorization/PanamaVectorizationProvider.java

It looks like lucene will fallback to another implementation if prerequisites for usage of Java vector API are not in place.

See https://github.com/apache/lucene/blob/d54789681eb9f0cacd79d03c30c44de779fb1622/lucene/core/src/java/org/apache/lucene/internal/vectorization/VectorizationProvider.java#L123

 

Is this Ok ?
