----------------------------------------

In that case I'd close this JIRA as wont fix.  I think as an API it isn't that generally useful in the first place.  :-)  WDYT?

> Equivalent to Node.clearData(), but removes the children.
> Use case is trying to atomically remove everything under some structural node, while leaving the structural node in place. The best that can be done now is either:
> 1) Remove the node and re-add it, but this doesn't work for remote caches with INVALIDATION, since both the removal and the addition propagate as invalidation messages. Remote caches are left w/o the structural node. Plus it's not atomic.
> 2) Query for the children and remove them one by one.  Also not atomic, plus if lockParentForChildInsertRemove is false you have to deal with other threads possibly adding new children while you are removing.
