> Key: CALCITE-5121
> URL: https://issues.apache.org/jira/browse/CALCITE-5121
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.30.0
> Reporter: Gregory Hart
> Priority: Major
> Labels: pull-request-available

> The documentation for org.apache.calcite.avatica.Handler#onConnectionInit states that a SQLException should be thrown "on error". However, the implementation of onConnectInit in org.apache.calcite.jdbc.Driver allows for other types of exceptions to be thrown. This also breaks the documentation contract for java.sql.Driver#connect since a RuntimeException could be throw instead of the expected SQLException.
> *Steps to reproduce:*
> DriverManager.getConnection("jdbc:calcite:schemaType=JDBC;schema.jdbcUrl=jdbc:invalid:");
> *Expected result:*
> A SQLException is thrown
> *Actual result:*
> A RuntimeException is thrown
> {code:java}
> java.lang.RuntimeException: Error instantiating JsonCustomSchema(name=adhoc)
