All subsequent calls to Neo4j freezes after handling a ClientException from @Index(unique=true)

QUESTION

All subsequent calls to Neo4j freezes after handling a ClientException from @Index(unique=true)

Asked 2017-May-30 at 17:13

I have a Spring boot application that has an Entity with an uniqueness constraint on a field.

im running spring-boot, spring-data-neo4j, neo4j-ogm, bolt-driver and the neo4j 3.2 docker image.

When i run my IT tests, i first persist some data, then i try to persist the same data to get the constraint to trigger.

The uniqueness constraint kicks in as expected in and a ClientException is thrown. This is caught and a proper exception is returned to the client.

Then in the following test i just try to save some data and suddenly the server just freezes when it runs the save() in the GraphRepository.

So my question is why does neo4j completly freeze in my case in all following transactions after a ClientException has been thrown due to a uniqueness constraint has kicked in. Logs say nothing, neo4j debug.log says nothing.

If i run each test separate, they both pass. Run together, it freezes neo4j in the test after the constaint has been tested.

ANSWER

After getting help on the neo4j-user slack the problem was that the drivers had problems closing the sessions when the transaction was closed.

This got fixed in version 2.1.3 of the bolt-driver in the neo4j-ogm.

So bumping the ogm version from 2.1.2 -> 2.1.3 resolved this issue.

related issue: Make rollback close bolt session when transaction is closed

related issue for the java-driver: java-driver version 1.3.1
