Description

Classes from sun.* should not be used as specified in:
http://www.oracle.com/technetwork/java/faq-sun-packages-142232.html

ImageIO is available since java 1.4. I have tested it using java 1.4 version and it works. This change has already be implemented in cocoon 2.2.1 version as in: https://issues.apache.org/jira/browse/COCOON-2327

I have a patch which is pretty much the same as the one in COCOON-2327 only differences are that import of SystemUtils is removed and It is not using generics to keep compatibility with java 1.4.

Additionally this change allows cocoon-core 2.1.13-dev to compile in java 1.7
