> After recreation of previously dropped SQL index (in persistent mode), root
> page of new index B+ tree may contain links to data entries from previous
> index tree. If these entries were removed or relocated to another data page,
> attempt to dereference these links may throw AssertionError or even cause JVM
> crash.
> Patch with reproducer is attached.
> P.S. Please note that with IGNITE-4958 fix old invalid links may refer to
> non-data page - it might have been recycled into page with any other type.
> Such case will cause AssertionError on page read lock attempt. Rolling back
> IGNITE-4958 may help with debugging.
