[jira] Created: (IVY-618) NPE in case of eviction
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...

[jira] Resolved: (IVY-618) NPE in case of eviction
Posted by "Gilles Scokart (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/IVY-618?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gilles Scokart resolved IVY-618.
--------------------------------
Resolution: Fixed
I have added a unit test that triggered to problem and a fix for it.
The fix doesn't roolback the change in IVY-603. It just handle the case where the desriptors are not loaded by reporting a "?" for the status.
