Ignacio Coloma commented on IVY-379:
------------------------------------
There is another (non-related) issue, but maybe it's not worth it opening a new
JIRA issue.
I obtained a NPE at IvyNodeEviction$EvictionData:
java.lang.NullPointerException
at
org.apache.ivy.core.resolve.IvyNodeEviction$EvictionData.<init>(IvyNodeEviction.java:42)
at
org.apache.ivy.core.resolve.IvyNodeEviction.markEvicted(IvyNodeEviction.java:240)
at org.apache.ivy.core.resolve.IvyNode.markEvicted(IvyNode.java:1083)
at
org.apache.ivy.core.resolve.ResolveEngine.getDependencies(ResolveEngine.java:446)
It the javadoc is not outdated, a null check would be needed before the for
loop at IvyNodeEviction.java, because "selected" can be null:
---> private Collection _selected; // Collection(IvyNode); can be null
in case of transitive eviction
private String _rootModuleConf;
public EvictionData(String rootModuleConf, IvyNode parent,
ConflictManager conflictManager, Collection selected) {
_rootModuleConf = rootModuleConf;
_parent = parent;
_conflictManager = conflictManager;
_selected = selected;
----> for (Iterator iter = selected.iterator(); iter.hasNext();) {
// here happens the NPE
As I said, maybe opening a separate JIRA was a bit too much for such a small
bug.
