----------------------------------

Hi, 

Its getting reproduced only in NFT envs where test is run on huge data.

Can you share all possible reasons for this failure?

> Data is getting fetched from Oracle DB but while mapping it back to JPA 
> object, it gets null. This can be seen through Dynatrace that SQL returns row 
> result but JPA resultset is getting null.
> Query is quite simple and just fetching the record based on primary key. 
> Although another field is being passed in where clause with primary key but 
> it returns single row.
> Also, same jpa query provides results (same input) several times before.
> We enabled jpa logs and see query runs fine on DB. 
> Is there any thresold due to which JPA not working as expected? Any 
> suggestions to handle this ?
