Revision: 1650347
Author: adrianc
Date: 08 January 2015 17:53:59
Message:
Some small fixups for some of my previous commits.
----
Modified : /ofbiz/trunk/framework/entity/src/org/ofbiz/entity/util/EntityClassLoader.java
Modified : /ofbiz/trunk/framework/base/src/org/ofbiz/base/util/UtilURL.java



We have found in one of our production servers that 

url = loader.getResource(resourceName);

has caused locking and looking at the stack trace (from jstack) there are numerous threads
waiting on locks from within this method

I propose the cache gets added back (we have done this as a patch on our systems with no ill
effect)

FYI - The commits are in reference to the EntityClassLoader which is not used and does not
work see OFBIZ-6210
