Unused imports

I'm getting a lot of unused import warnings when I look at the source
code in Eclipse.  Can they be removed?

Here's a list:

SDataSet.java:
import java.util.Arrays;

SFieldBoolean.java:
import java.sql.ResultSet;
import simpleorm.utils.SException;

SFieldMeta.java:
import simpleorm.utils.SLog;

SFieldScalar.java:
import simpleorm.dataset.validation.SValidatorMaxLength;

SQuery.java:
import java.util.StringTokenizer;

SDriverH2.java:
import simpleorm.dataset.SFieldScalar;
import simpleorm.dataset.SRecordMeta;
import simpleorm.sessionjdbc.SDriver;
import simpleorm.sessionjdbc.SGenerator;

SDriverHSQL.java:
import simpleorm.dataset.SFieldScalar;
import simpleorm.dataset.SRecordMeta;
import simpleorm.sessionjdbc.SGenerator;

SDriverInterbase.java:
import simpleorm.dataset.SFieldMeta;

SDataLoader.java:
import simpleorm.dataset.SFieldMeta;

SSessionJdbc.java:
