Hi, Is there JDBC driver support for JDK 17? I’m using the latest driver found in version 20.1 and it works from my client application if I run JDK 11. However upgrading the client application to JDK 17 yields the following error ```auto java.sql.SQLException: Failure in connecting to Dremio: cdjd.com.dremio.exec.rpc.RpcException:

@balaji.ramaswamy Apache arrow flight JDBC driver working fine in JDK 17 for connecting dremio. Is it supported by dremio officially? Since many organization is migration from JDK11 TO JDK 17 and JDK11 going to be obsolete soon post which JDBC driver will not be compatible in JDK17. Please advise. ---

I’m not an employee so I can’t speak to what is official and what isn’t but it is listed in the Dremio documentation at [Dremio](https://docs.dremio.com/software/drivers/arrow-flight-sql-jdbc-driver/) ---

Hi, Any update on this? I face a similar issue if I change the java version from 11 to 17 in the client side. Both Arrow and JDBC drivers stop working.

@mversiani looks like a Java version issue, what is your Java version on the server side? ---

Hi @balaji.ramaswamy, I’m using openjdk 17.0.10 2024-01-16 on the client side and openjdk 11.0.22 2024-01-16 on the server side. ---

@mversiani Is it possible to upgrade to Dremio 24.x and try the same? ---

@balaji.ramaswamy , I’m already using the version 24.2.6. I think it’s due to the java version on the client side. Maybe I’m wrong, is there any other requirement or configuration for the clients to be able to connect to Dremio using the JDBC driver? ---

@mversiani Sorry my bad, currently Dremio only supports JDK 8 or 11 Once 25.x is out, it will no longer support JDK 8 ---

@balaji.ramaswamy , so you mean maybe the version 25 of Dremio Server (not yet available) could solve it? Don’t you think it could be something I should do in the client side to make it work keeping java 17? thanks for help. ---

@mversiani Is there a requirement that you need Java 17 on the client? ---

If I downgrade to java 11 it works. But I found a solution with the Dremio support team: > export JAVA\_TOOL\_OPTIONS=“–add-opens=java.base/java.nio=ALL-UNNAMED” With this env variable both drivers, the classic JDBC and the flight JDBC, work using the java jdk 17 in the client side.
