[infinispan-dev] being able to preload data from a JdbcStringBasedCacheStore

Hello, as Mircea pointed out that the JdbcStringBasedCacheStore should be used instead of the JdbcBinaryCacheStore when possible, in particular when I'm under control of all key types - which is the case for the LuceneDirectory - so I'd like to use it. Unfortunately I just opened ISPN-579, and this issue also points out that this Store implementation actually doesn't support preloading, a natural consequence from the fact that the Key2StringMapper is missing the inverse transformation from String to Object. I'd like to define the interface for the inverse transformation too, I think it would be useful - possibly not making it mandatory, by allowing to throw a non-supported-operation exception or extending the interface to a new one having the missing method. WDYT?
