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 line 98 in UtilURL.java

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

Thanks: Gareth Carter for report and suggestion
