Michael, it seems that fix will be quite simple.
I could review and merge your pull request.
But please, do not delay with your fix - we are going to release soon.

> Given a SQLite database file that contains tables that are not inside a schema, i.e.:
> {code}
> sqlite> .schema
> CREATE TABLE INFO_LIST(aType varchar(64), aCode varchar(128), aInt INTEGER, aDate datetime,
PRIMARY KEY(aType, aCode));
> {code}
> The ignite-import-schema.sh tool generates a {{CacheConfig.java}} with the following
schema:
> {code}
> type.setDatabaseSchema("null");
> {code}
> When the {{CacheAbstractJdbcStore#EntryMapping}} class is instantiated, it performs the
following check:
> {code}
> fullTblName = F.isEmpty(schema) ? tblName : schema + "." + tblName;
> {code}
> and generates the following {{insQuery}} and {{updQuery}}
> {code}
> INSERT INTO null.INFO_LIST(aType,aCode,aInt,aDate) VALUES(?,?,?,?)
> UPDATE null.INFO_LIST SET aInt=?,aDate=? WHERE (aType=? AND aCode=?)
> {code}
> This is incorrect, and the code generated in CacheConfig.java should be:
> {code}
> type.setDatabaseSchema(null);
> {code}
> i.e., *without* quotes.  Then the {{F#isEmpty(schema)}} call returns the correct value.
> *Right now, the code generated by ignite-import-schema.sh is not usable without finding
this problem one's self, and fixing it.*
