NPE in case of eviction
-----------------------
Key: IVY-618
URL: https://issues.apache.org/jira/browse/IVY-618
Project: Ivy
Issue Type: Bug
Affects Versions: 2.0.0-beta-1
Reporter: Gilles Scokart
Priority: Blocker
Fix For: 2.0.0-beta-1
Since the fix of IVY-603, we have NPE in some cases when we have evicted
modules.
(I have slightly updated the code to have a more precise trace)
java.lang.NullPointerException: getDescriptor() is null for [ junit | junit |
3.8.1 ]

Reverting the change done to ResolveEngine.java in IVY-603 seems to fix the
regression. But the right fix might be to fill the descriptor even when the
module is evicted...
