Hi,
I'm using Tomee 10.0.1 with JDK 21. One of my end-points is using Lucene index
for some search result. The Lucene jar is version 10.2.1, which is using the
new Vector API.
When using this library I notice some warnings in the log:
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
03-Jun-2025 09:40:17.597 WARNING [http-nio-8091-exec-2]
org.apache.lucene.internal.vectorization.VectorizationProvider.lookup Java
vector incubator module is not readable. For optimal vector performance, pass
'--add-modules jdk.incubator.vector' to enable Vector API.
To avoid these messages, I tried to add args to my tomee-maven-plugin
configuration:
<args>enable-native-access=ALL-UNNAMED</args>
<args>add-modules=jdk.incubator.vector</args>
What I noticed is that only the last one will be taken into consideration.
Meaning that with these settings I will get the first WARNING, and a message
indicating that the Vector API is found. If I switch the args, I will get the
last WARNING.
Is this a know problem with the plugin configuration?
Best regards,
Roar Brænden
