Why to Mark as Final when accessed from Inner Class

[Ragupathirajan Venkatesan]

Dear All,

I have method level local variable and i am using inside the inner class with in that method. System asking me to declare it has final variable. Please advise the reason behind that. example below.
public HashMap getValues(){
HashMap csvMap=null;
return (Forum) jdbcTemplate.queryForObject(query, new Object[] { Integer.valueOf(forumId) },
new RowMapper() {
public Object mapRow(ResultSet resultSet, int rowNum) throws SQLException {
while(resultSet.next){
csvMap.put(resultSet.getString(1),resultSet.getString(2));
}
}
});
}
csvMap is the local variable I am using.
