Error getting the value from the KeyStore file

Version: Windchill 12.1

Use Case: Errors in logs at Windchill startup, but it starts.

Description:

This has been asked before, but as there's two different related articles I'm asking again.

There's errors in logs at Windchill startup:

com.ptc.paa.config.keystore.PAAKeyStore  - Error getting the value from the KeyStore file java.security.KeyStoreException: Could not load keystore file.

However, Windchill starts and runs fine.

There's two different solutions. One says to delete files and restart, another says to run -ant to recreate keystore. Which is enough?
