Replace javax.imageio.spi.ServiceRegistry with java.util.ServiceLoader

[Raj Saini]

Hi,

org.ofbiz.base.util.UtilObject#getObjectFromFactory class uses 
*javax.imageio.spi.ServiceRegistry *class to load DelegatorFactory 
implementation. ServiceRegistry class internally uses sun.misc.Service 
class which is internal to sun and may not be part of other JDKs.

Starting with JDK 1.6, java.util.ServiceLoader class is provided to 
replace the javax.imageio.spi.ServiceRegistry class and this class does 
not depend on sun.misc.Service class. This is minor two line code change 
and if community agree I can provide the patch.

Thanks,

Raj
