Unsupported jdbc driver classname with com.ibm.as400.access.AS400JDBCDriver

Hello

I am trying to create a Glue Crawler using JDBC driver jt400-20.0.7.jar (obtained from https://mvnrepository.com/artifact/net.sf.jt400/jt400), and getting error "Unsupported jdbc driver classname" . [This was reported also for AWS Advanced JDBC Driver](https://github.com/awslabs/aws-advanced-jdbc-wrapper/issues/653), and apparently the problem is Glue doesn't support all JDBC drivers.

I also tried to manually creating a job using the custom JDBC Connection, and it failed, and I think the root failure was “WARNING - Glue ETL Marketplace - Connection _my connection name_ is not a CUSTOM or Marketplace connection, skip jar downloading for it”.

Could you please confirm whether is possible to use Glue with any JDBC Driver, such as this DB2 one? Or is Glue limited to a handful of supported JDBC Drivers?

Thanks and best regards

No repository file, test, or entry point is identified in the issue. Start by reviewing the AWS Glue Crawler and custom JDBC Connection scenarios described, then document whether the com.ibm.as400.access.AS400JDBCDriver and other custom JDBC drivers are supported and what configuration is required.
