New Revision: 812175

URL: http://svn.apache.org/viewvc?rev=812175&view=rev
Log:
https://issues.apache.org/jira/browse/EXTSCRIPT-11
adding the jci compiler facade, but the main issue here is that the entire pre jdk6 support needs a project reorg I am not sure if I really will drag this along especially since we have to target myfaces 2.0 as well
