fixed in svn r328639
> iterative removal of same-name sibling nodes might under certain
> circumstances throw unexpected exceptions
> ----------------------------------------------------------------------------------------------------------
>
> Key: JCR-261
> URL: http://issues.apache.org/jira/browse/JCR-261
> Project: Jackrabbit
> Type: Bug
> Components: core
> Environment: svn r328092
> Reporter: Stefan Guggisberg
> Fix For: 1.0
>
> code fragment to reproduce the issue:
> // setup test
> if (root.hasNode("tmp")) {
> root.getNode("tmp").remove();
> session.save();
> }
> Node tmp = root.addNode("tmp");
> for (int i = 0; i < 4; i++) {
> Node a = tmp.addNode("a");
> System.out.println("added " + a.getPath());
> }
> session.save();
> // iterative removal of same name sibling child nodes
> NodeIterator ni = tmp.getNodes();
> while (ni.hasNext()) {
> Node n = ni.nextNode();
> System.out.println("removing " + n.getPath());
> n.remove();
> tmp.save();
> }
> console output:
> added /tmp/a
> added /tmp/a[2]
> added /tmp/a[3]
> added /tmp/a[4]
> removing /tmp/a
> removing /tmp/a
> removing /
> javax.jcr.RepositoryException: /: cannot remove root node
> at org.apache.jackrabbit.core.ItemImpl.internalRemove(ItemImpl.java:766)
> at org.apache.jackrabbit.core.ItemImpl.remove(ItemImpl.java:997)
> at org.apache.jackrabbit.core.Test.main(Test.java:141)
> note that the msg of the exception is misleading: the above code did never
> try to remove
> the root node.
> the exception is caused by a bug in CachingHierarchyManager which fails to
> update
> the cache correctly.
> btw: if you comment the first logging stmt, i.e.
> //System.out.println("added " + a.getPath());
> the problem doesn't occur anymore.
