neo4j constraint deleted node

问题

I have an issue where a constraint exception is thrown on a deleted node.

The cypher statement "match (n) where ID(n)=272 return ID(n),n" returns 0 rows, but when I try to create a new record that previously had a constrained value, the exception below) is still throw.

FYI, the constraint is on a property containing a String[] - maybe constraint uniqueness is broken with arrays?

Working with NEO4J 2.0.0M06 using the Java API (OpenJDK 7) on Ubuntu 12.04 via the nodejs/java npm (v sweet combo:) )

Temporary workaround: drop the constraint and re-create it (all worked from then on).

Is there a tool/schema command to force Neo to check integrity?
