URL: https://issues.apache.org/jira/browse/LOG4J2-1839
Project: Log4j 2
Issue Type: Improvement
Components: Appenders

.setColumnConfigs(columnConfigs)
.setConnectionSource(connectionSource)
.setTableName(tableName)
.withName(name)
.withIgnoreExceptions(ignoreExceptions)
.withFilter(filter)
.build();

I did not set any columnMappings. After providing
.setColumnMappings(columnMappingJDBC)
to my builder it worked OK. I would suggest to either improve the javadoc or
add NULL check in JdbcDatabaseManagerFactory.createManager
