Subject Re: Index already exists exception

So to restate, without the readSchema option, the mapping tool  
doesn't know the existing index names or which columns have indexes.   
This means that indexes are created blindly, and there could very  
well be an index conflict for an existing table created by OpenJPA.

Assuming that is true, shouldn't we change failed index creation  
without readSchema to a warning instead of an error.
