markhoerth opened a new issue, #14307:
URL: https://github.com/apache/gravitino/issues/14307
### Version
main branch (2.0.0-SNAPSHOT, eb988d1)
### Describe what's wrong
The launch scripts accept Java 17 or newer, but add the `--add-opens` flags
only when the JVM is
exactly 17:
- `bin/gravitino.sh.template:158`
- `bin/gravitino-iceberg-rest-server.sh.template:157`
- `bin/gravitino-lance-rest-server.sh.template:157`
- `bin/gravitino-optimizer.sh.template:53`
each guarded by `if [[ "$JVM_VERSION" -eq 17 ]]`. On Java 21 none of the
flags are set. Arrow,
used by the Lance table operations, then fails to initialize, and creating a
Lance table through
the Gravitino API returns 500.
### Error message and/or stacktrace
```
HTTP 500 {"type":"ExceptionInInitializerError","message":"Server error while
processing request: java.lang.ExceptionInInitializerError"}
Caused by: java.lang.RuntimeException: Failed to initialize MemoryUtil. You
must start Java with
`--add-opens=java.base/java.nio=org.apache.arrow.memory.core,ALL-UNNAMED`
at org.lance.Dataset.create(Dataset.java:139)
at
org.apache.gravitino.catalog.lakehouse.lance.LanceTableOperations.createDataset(LanceTableOperations.java:486)
```
### How to reproduce
1. Start the server with `JAVA_HOME` pointing at a Java 21 JDK.
2. Create a lakehouse-generic catalog and a schema, then create a table with
`"properties": {"format": "lance", "location": "/tmp/lance_t"}`.
3. The response is 500. The same steps on Java 17 succeed.
### Additional context
Requirement: the scripts set the flags for every Java version they accept
(17 and newer).
