We'd found a bug while switching to the latest OJDBC11 version 23.8.0.25.04. Is there an official place to report the issue?
The driver reports a java.sql.SQLSyntaxErrorException: ORA-00900: invalid SQL statement Caused by: Error : 900, Position : 12, SQL = select*from dual, i.e. it now requires a blank between select and asterix/star.
Surprisingly, it is not a problem if the space is missing in an inner query, for example ‘select *from(select*from dual)’ is executed without problems.
