>                 Key: JCR-542
>                 URL: https://issues.apache.org/jira/browse/JCR-542
>             Project: Jackrabbit Content Repository
>          Issue Type: Improvement
>          Components: jackrabbit-core
>    Affects Versions: 1.0.1
>            Reporter: Florent Guillaume
>            Priority: Minor

> During schema migrations, it is often the case that an item definition changes. For instance,
a property may move from type Long to type String.
> However when jackrabbit is restarted, it's impossible to remove any node having "old"
properties:
> javax.jcr.nodetype.ConstraintViolationException: no matching property definition found
for {}myprop

>         at org.apache.jackrabbit.core.ItemImpl.internalRemove(ItemImpl.java:848)
>         at org.apache.jackrabbit.core.ItemImpl.remove(ItemImpl.java:1034)
> I don't understand enough of the internals to know if it's easy, but could something
be made more lenient to allow such removals?
