New Revision: 1868666

URL: http://svn.apache.org/viewvc?rev=1868666&view=rev
Log:
Fixed: Use ‘ConcurrentHashMap’ to avoid ‘ConcurrentModificationException’
(OFBIZ-11258)

When trying to load components in their dependency order the
‘toBeLoadedComponents’ map is modified while being iterated over which
is not safe for non-concurrent maps.
