Steps to reproduce:
- Setup Camunda DB schema based on 7.12 on Postgresql
- Break the DB schema, for example, by deleting the column ACT_RU_JOB#REPEAT_OFFSET_
- Start Camunda (with jdbcBatchProcessing = true)
- Deploy a BPMN process containing a timer event
- Start a process instance
Expected behavior:
- The engine fails to insert the timer because of the missing column REPEAT_OFFSET_
- The respective exception message contains the database exception pointing out that the column REPEAT_OFFSET_ is not present, e.g.,
ENGINE-03004 Exception while executing Database Operation 'INSERT TimerEntity[ca202cdf-7a75-11ea-86ee-0242ac12000a]' with message ' ### Error updating database. Cause: org.postgresql.util.PSQLException: ERROR: column "repeat_offset_" of relation "act_ru_job" does not exist Position: 397 ### The error may involve org.camunda.bpm.engine.impl.persistence.entity.JobEntity.insertTimer-Inline ### The error occurred while setting parameters ### SQL: insert into ACT_RU_JOB ( ID_, TYPE_, LOCK_OWNER_, LOCK_EXP_TIME_, EXCLUSIVE_, EXECUTION_ID_, PROCESS_INSTANCE_ID_, PROCESS_DEF_ID_, PROCESS_DEF_KEY_, RETRIES_, EXCEPTION_STACK_ID_, EXCEPTION_MSG_, DUEDATE_, REPEAT_, REPEAT_OFFSET_, HANDLER_TYPE_, HANDLER_CFG_, DEPLOYMENT_ID_, SUSPENSION_STATE_, JOB_DEF_ID_, PRIORITY_, SEQUENCE_COUNTER_, TENANT_ID_, CREATE_TIME_, REV_ ) values (?, 'timer', ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 1 ) ### Cause: org.postgresql.util.PSQLException: ERROR: column "repeat_offset_" of relation "act_ru_job" does not exist ...
Observed behavior:
- The engine fails to insert the timer because of the missing column REPEAT_OFFSET_
- But the exception message does not provide any information on while the insert failed, e.g.,

Hint:
- To get the actual exception, the user has to disable JDBC batch processing in the process engine configuration.
- For example, the difference between 7.11.0 and 7.12.0 is:
- 7.11.0: The method #flushDbOperationsException() is called which went over #getNextException() to collect all exceptions, see https://github.com/camunda/camunda-bpm-platform/blob/7.11.0/engine/src/main/java/org/camunda/bpm/engine/impl/db/entitymanager/DbEntityManager.java#L362
- 7.12.0: The method #flushDbOperationException() is called which gets only the exception which will be used to get the exception message but it does not "resolve" the next exceptions by calling #getNextException().
- With the 7.10.0 and 7.11.0 the engine logged, for example, DB2 SQL exceptions like this:
