JDBC Driver add support for OpenJDK 17

[wise-coders]

I have tested the JDBC driver under OpenJDK17, and does not work. I tested ignite-core-2.14.0.jar. Same driver works fine with OpenJDK15.

1. Which JDBC driver did you try - "thin" or full?
2. What is the error?

[wise-coders]

I tried the full. They are part of the same library, ignite-core-2.14.0, right? I am getting an empty ( null ) connection. Changing to OpenJDK15 works fine.

Did you provide all required JVM flags?

--add-opens=jdk.management/com.sun.management.internal=ALL-UNNAMED \
--add-opens=java.base/jdk.internal.misc=ALL-UNNAMED \
--add-opens=java.base/sun.nio.ch=ALL-UNNAMED \
--add-opens=java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED \

No, I don't set any flags. I use the library as JDBC driver, to connect to the database. The library is loaded in a database client, Dbschema.

@wise-coders Hi! It is advisable to use a jdbc-thin one. Could you please share here your connection string?

[wise-coders]

Here is the URL: jdbc:ignite:thin://{HOST}[:{PORT}] port defaults to 10800
