About duplicate aliases in MSCAPI keystore

I am looking at this bug

   MSCAPI doesn't list aliases correctly

For the Windows-MY keystore, if you call setEntry() on the same alias (say, "alias") twice, the keystore shows only one entry with the alias. But after closing and re-loading, two are shown, "alias", and "alias (1)".

I know the Windows tool certutil.exe can be used to add 2 entries with the same name, and both will be stored. In this case, if we use Java to load the keystore, we will have to list both, with different aliases.

But do we really need to support it on the Java side? Can we just overwrite the previous entry when setEntry() is called on an existing alias?

Was this designed as a feature?
