We have an entity named as MFAFIDO2CredentialEntry,
right now the service builder will generate variable names mfafido2CredentialEntry*,
while desired variable names would be mfaFIDO2CredentialEntry*

For example, in MFAFIDO2CredentialLocalServiceBaseImpl, there will be class member variable that can be inherited/used by MFAFIDO2CredentialLocalServiceImpl.

So when I try to use those class member variables from LocalServiceBaseImpl in LocalServiceImpl, it will look like:

	MFAFIDO2CredentialEntry mfaFIDO2CredentialEntry =
			mfafido2CredentialEntryPersistence.fetchByUserId(userId);

	@Override
	public MFAFIDO2CredentialEntry fetchMFAFIDO2CredentialEntryByCredentialId(
		String credentialId) {

		return mfafido2CredentialEntryPersistence.fetchByCredentialId(
			credentialId);
	}

Same thing for accessing variables from persistence layer.

Here is the diff change between without applying the fix and after applying the fix:
