Summary:	Add/Remove operations on a VDB should block other operations on the VDB

Whiteboard:
Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	According to http://wiki.eclipse.org/Eclipse/UNC_Paths, the java.net.* libraries do not handle UNC paths as well as org.eclipse.core.runtime.URIUtil does. As a result, when UNC paths were being used, VDB dependencies were not being resolved correctly and an ArrayIndexOutOfBoundsException was being thrown. The VdbModelEntry.synchronizeModelEntry method has been modified to use URIUtil to get the URI and no exception is encountered.	Story Points:	---

Description Marc Shirley 2011-10-24 19:24:54 UTC

++ This bug is a clone of bug 781035 ++

Help Desk Ticket Reference: https://c.na7.visual.force.com/apex/Case_View?id=500A0000008SP5t
Steps to Reproduce: In workspace stored on network filesystem, perform below steps with any existing VDB.
1) Remove model from VDB
2) Immediately add same model back into VDB
Workaround Description: The network filesystem is mapped to a drive letter in a Windows environment.  Instead of using the UNC Path for the model, use the mapped drive, to import the model.
project_key: SOA

As adding/removing objects from a VDB results in filesystem operations of adding/removing indexes, this should result in a blocking of additional operations against the VDB.  If latency with the filesystem is large enough (for example, on a network filesystem) and no blocking is performed, multiple operations can be performed on the VDB resulting in the below exception:
!MESSAGE Unhandled event loop exception
!STACK 0
java.lang.ArrayIndexOutOfBoundsException: 0

The fix broke on linux and we double-encoding the URI causing same ArrayIndexOutOfBoundsException.

commit additional fix for handling windows UNC path issue.  avoids conversion of EMF and java.net URI altogether due to UNC path issues.
