java 8 date support in TaskExecution breaks DB2 support about spring-cloud-task HOT 4 CLOSED

Hello,
I created a sample task from start.spring.io that used Spring Cloud Task on a DB2 (ibmcom/db2:latest) instance but was unable to reproduce . Can you provide a sample project the reproduces the problem?

from spring-cloud-task.

Hello,

I'm not sure what's the best way to create a test to reproduce it.
I'll try to give a bit more context when and how the problem occurs:

We register our Task in SCDF server (this application is also using DB2). The Task is registered as boot3 application, and thus using the BOOT3_ schema tables.
Then the task is launched via the SCDF (via Inteface / REST / CLI)
We are using Kubernetes as Target platform the run the Task (should not really matter I guess)
By launching from SCDF a new record is inserted in the table BOOT3_TASK_EXECUTION by the server before running our task (this record does not yet have a value in the START_TIME collumn)
The id of this new record is passed as argument to the Sping Cloud Task application (--spring.cloud.task.executionid=XXX')
When the Task is started it's trying to load the record from the database associated with this executionId
(org.springframework.cloud.task.repository.dao.JdbcTaskExecutionDao.getTaskExecution)

This is where it fails, the getTaskExcetion throws an exception in the mapRow function.

Caused by: java.lang.NullPointerException: Cannot invoke "java.sql.Timestamp.toLocalDateTime()" because "<local4>" is null
