[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1213) TreeCache expires parents that have children

Todd Ciezadlo commented on ISPN-1213:
-------------------------------------

After testing, the work-around noted above only works for simple cases.  For example, it works with the attached ExpirationTest.  But it causes problems for more complex cases and should be avoided for anything non-trivial.

I agree that eviction will need to be reinvented for TreeCache.

> TreeCache parents expire according to the max-idle value even if they contain children.  This puts the tree cache in an inconsistent state since the "dangling" children can be retrieved through TreeCache.get(FQN, String) calls, but cannot be traversed to through TreeCache.getRoot() and Node.getChildren() calls.
> Attached unit test to to reproduce.
