Ramesh Reddy commented on TEIID-479:
------------------------------------

There three different this issue will be fixing 

1) Convert the Embedded's runtime engine to use "delegating" class loader instead of the "non-delegating" currently in use.
2) The directory where the runtime libraries are dynamically loaded from should be configurable.
3) The extensions mechanism, needs allow configuration to specify multiple directories.

> The non-delegating classloader for lib and patches entries will create problems if any of the jars duplicate classes from a higher level classloader - without overriding all of the referenced classes.  See TEIIDDES-141 for a similar situation in a designer install.
