Hello,
TLDR : To be able to build and run Zeppelin on my Debian 12 computer, I
need to upgrade it to Java 17.
Some tests aren't running after doing that.
But I don't know what tests weren't working under Java 11 yet,
to compare that list with the one I have that aren't working on my computer.
May someone run something like a
mvn clean install -fn
and list me the failling tests ?
Thanks!

Long version:
Allow Apache Zeppelin to run with Java 17
on an experimental fork from a recent master
:https://github.com/apache/zeppelin/compare/master...mlebihan:zeppelin:jdk_17
I faced few problem due to unexperience, here what I've currently done to
advance:
1. Problem with a downloading attempt from a SNAPSHOT repository that doesn't
exist anymore
- temporary removed flink
2. Cassandra test content is hanging
- temporary removed Cassandra test content that was hanging (in setup, I
guess)
3. Completed default`conda` Python environment (currently installing itself
with a Python`3.12.9` version) with:
```bash pip install grpcio
pip install ir
pip install pandas
pip install pandasql
pip install protobuf
``` 4. add-exports, add-opens added to`pom.xml` to allow running on Java 17
- using`module-info.java` would be better (but longer to settle)
but some code is attempting to import internal packages from GSon,
preventing their use yet.
5. Two tests of`RemoteInterpreterTest` cannot run if your computer isn't a
localized`en` one
test will search for messages like`command not found` when my french OS will
deliver:`commande introuvable`.
- I've added a package named`org.apache.zeppelin.util.debug` that contains a
class to help in debugging.
Its goal is to gather error information whatever it occurred in a
synchronous or asynchronous task, within an exception or not.
- Replaced assertions
in`zeppelin-zengine/src/test/java/org/apache/zeppelin/interpreter/remote/RemoteInterpreterTest.java`
- in`testFailToLaunchInterpreterProcess_ErrorInRunner`
:`assertEquals(ProcessLauncher.ERROR_STATUS_COMMAND_NOT_FOUND,
PostMortem.currentError().interpretedExitCode(), "Command should not be found")` -
in`testFailToLaunchInterpreterProcess_Timeout` :`assertEquals(ProcessLauncher.ERROR_STATUS_TIMEOUT,
PostMortem.currentError().interpretedExitCode(), "Command should had timed out");` 6. Run
a`mvn clean install -Dzeppelin.interpreter.conda.env.name=base -fn` Failed projects are these:
