We recently migrated our code using TREP EMA API using jdk 1.8. After that we faced 2 times below ConcurrentModificationException error in PROD env and hence our process terminated. Then we had to start our service again. Kindly help to fix this issue ASAP.
We made the connection to TREP using DACSID provided by MDS team and reference code EMA Consumer - Requesting and displaying MarketPrice data shared by Umer Nalla/Team.
To clarify if this is EMA bug/non-support feature or improper implementation/configuration in application level with the development team, you can submit your problem to the development directly via GitHub at
Then, click "New issue" button. Hence, you can communicate and follow up with the development team directly.
Hi Nipat Kunvu/Team,
I created New Issue on GitHub as you advised, But no response yet since Aug 21.
