QueryException: Incorrect arguments to mysqld_stmt_execute on inserting an "emptyString"-Lob with JPA

JPA-Mapping:
@Entity
public class someEntity

{ ... @Lob private String property = ""; ... }

Since version 1.5.8 persisting a new instance of 'someEntity' fails with following exception:

If the property contains a filled string, the entity will be persisted successfully.
Using an earlier Connector-version (e.g. 1.5.7) does not cause the exception.
