MariaDB Connector 3.x results in "class [B cannot be cast to class java.lang.String"

See original GitHub issue

Environment

Liquibase Version: 4.7.1

Liquibase Integration & Version: maven

Liquibase Extension(s) & Version: liquibase-percona 4.8.1-SNAPSHOT

Database Vendor & Version: MariaDB 10 + MariaDB Connector < 3.0.4

Operating System Type & Version: Linux

Description

In the liquibase-percona extension I use the snapshot feature (SnapshotGeneratorFactory.getInstance().createSnapshot(...)) to determine existing foreign keys of a table.

With MariaDB Connector 3.0.3 this results in an “java.lang.IllegalArgumentException: Unexpected datatype NULL”. The same problem is also described at https://forum.liquibase.org/t/fresh-install-giving-unusual-unexpected-datatype-null/6170

Here's the full stacktrace

This is the query, that is being executed by liquibase:

SELECT TABLE_SCHEMA TABLE_CAT, NULL  TABLE_SCHEM,  TABLE_NAME, IF(TABLE_TYPE='BASE TABLE' or TABLE_TYPE='SYSTEM VERSIONED', 'TABLE', TABLE_TYPE) as TABLE_TYPE, TABLE_COMMENT REMARKS, NULL TYPE_CAT, NULL TYPE_SCHEM, NULL TYPE_NAME, NULL SELF_REFERENCING_COL_NAME,  NULL REF_GENERATION

FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA='testdb' AND TABLE_NAME='address' AND TABLE_TYPE IN ('BASE TABLE','SYSTEM VERSIONED') ORDER BY TABLE_TYPE, TABLE_SCHEMA, TABLE_NAME

Steps To Reproduce

This shows up an an integration test that uses the “dropForeignKeyConstraint” change together with liquibase-percona. See https://github.com/liquibase/liquibase-percona/pull/180 and the build logs there. The integration test is this: https://github.com/liquibase/liquibase-percona/tree/main/src/it/allChangesLiquibaseMariaDB just run with MariaDB Connecto 3.0.3 instead of 2.7.5.

Actual Behavior

  • java.lang.IllegalArgumentException: Unexpected datatype NULL

Expected/Desired Behavior

  • no exception

@kataggart The new release of mariadb connector/j is available now: https://github.com/mariadb-corporation/mariadb-connector-j/releases/tag/3.0.4

The problems with liquibase appear to be fixed now, so I’m closing this issue.
