Any action requred if I already upgraded to V605 iFix003?

Upgraded one customer's CLM environment last weekend from V604 to V605 iFix003.  Just noticed that iFix003a was released.  This is in the Readme file:

- Customers only need to deploy 6.0.5 iFix003a if they are in the process of upgrading to 6.0.5 from a previous 6.0.x release. - This has been released to resolve an issue that may occur when upgrading to 6.0.5, and will only occur if 6.0.5 iFix002 or 6.0.5 iFix003 was deployed as part of the upgrade. - The issue is that when running a repotools command as part of the upgrade, the following exception may occur in the repotools-rm_addTables.log file:2018-03-05 19:07:15,620 Uncaught Exceptionjava.lang.NullPointerException    at com.ibm.rdm.fronting.server.concurrent.RMListenableFutureTask.run(RMListenableFutureTask.java:75)- If a customer has already upgraded to 6.0.5 and are on 6.0.5 GA or 6.0.5 iFix001, then 6.0.5 iFix003a does not need to be deployed in place of 6.0.5 iFix003

During the upgrade I noticed the "Uncaught Exception" messages during the RM upgrade. The upgrade appeared to be successful otherwise and I've had no issues reported from the customer.

The readme file doesn't specify any actions if you've already upgraded.  Are there any concerns I should have?

Thanks,
Fran
