ConcurrentModificationException in
SessionItemStateManager.getIdOfRootTransientNodeState()
------------------------------------------------------------------------------------------
Key: JCR-2807
URL: https://issues.apache.org/jira/browse/JCR-2807
Project: Jackrabbit Content Repository
Issue Type: Bug
Affects Versions: 2.1.2
Reporter: Weston Bustraan
SessionItemStateManager.getIdOfRootTransientNodeState() is throwing a
ConcurrentModificationException on line 607:
Here's a snippet of the code:
{code}
for (NodeId id : candidateIds) {
if (nodeId.equals(id) || hierMgr.isAncestor(id,
nodeId)) {
// already a candidate or a descendant thereof
// => skip
skip = true;
break;
}
if (hierMgr.isAncestor(nodeId, id)) {
// candidate is a descendant => remove
candidateIds.remove(id);
}
}
{code}
Can't use Collection.remove(Object) in the middle of iterating. It should
probably be changed to use Iterator.remove():
{code}
Iterator<NodeId> nodeIdItor = candidateIds.iterator();
while (nodeIdItor.hasNext()) {
NodeId id = nodeIdItor.next();
if (nodeId.equals(id) || hierMgr.isAncestor(id,
nodeId)) {
// already a candidate or a descendant thereof
// => skip
skip = true;
break;
}
if (hierMgr.isAncestor(nodeId, id)) {
// candidate is a descendant => remove
nodeIdItor.remove();
}
}
{code}
Any idea what I could do differently to workaround the issue?
