could you use the other javadoc format ?

Line 44:                 
entity.setMacPoolRanges(rs.getString("mac_pool_ranges"));
i don't think swallowing an exception is a good practice:
If from some reason the column is missing - it means a required upgrade script 
wasn't executed for that specific environment which the user must be aware of.
Line 45:             } catch (SQLException e) {
Line 46:                 //that columns not there.
Line 47:             }
Line 48:             return entity;


Line 177: Override
the javadoc of updatePartial states only a certain fields should be updated in 
this context. Please update the javadoc of StoragePoolDAO.updatePartial() to 
reduce confusion (the javadoc is already not precise)

File 
packaging/dbscripts/upgrade/03_05_0300_add_mac_pool_ranges_to_storage_pool.sql:

Line 1: select fn_db_add_column('storage_pool', 'mac_pool_ranges', 'character 
varying(255)');
by defining a limit to the range field you actually limit the amount of ranges 
per data-center.

I have no anticipation nor the knowledge whether users might define more than 7 
ranges per data-center, but i wouldn't limit it without a good reason.
