Problems

1. In SuppressSqlExceptionsTest shouldThrowExceptionOnInsert_ColumnSizeExceeded & shouldThrowExceptionOnUpdate fails on MariaDB 10.0
2. SuppressSqlExceptionsTest#shouldThrowExceptionOnInsert_ColumnSizeExceeded fails on HistoryLevel == NONE
3. ManagementServiceTest fails on DB2

Root Causes

1. Maria DB 10.0 does not throw an exception when the column size is exceeded; instead, the string is truncated at 255 characters
2. The test is designed to be executed with a minimum history level of HISTORY_LEVEL_ACTIVITY
3. The alias RES is missing when selecting columns

Solutions

1. Add test annotation @RequiredDatabase(excludes = DbSqlSessionFactory.MARIADB)
2. Add test annotation @RequiredHistoryLevel(ProcessEngineConfiguration.HISTORY_ACTIVITY)
3. Add the RES alias when selecting columns
