Spring data gremlin makes it easier to implement Graph based repositories. This module extends Spring Data to allow support for potentially any Graph database that implements the Tinkerpop Blueprints 2.x API.

Test cases *.java::testCollectionsCascadeRemove() fail occasionally.

====Source code of test cases====

The source code of those test cases are at:

org.springframework.data.gremlin.object.core.repository.AbstractPersonRepositoryTest.java::testCollectionsCascadeRemove().

org.springframework.data.gremlin.object.jpa.repository.AbstractPersonRepositoryTest.java::testCollectionsCascadeRemove().

org.springframework.data.gremlin.object.neo4j.repository.AbstractPersonRepositoryTest.java::testCollectionsCascadeRemove().

Those test cases are used in sub-project 'spring-data-gremlin-orientdb', 'spring-data-gremlin-tinker' and 'spring-data-gremlin-titan'.

====Reproducing frequency====

When executing 'gradle test' several times in main project or above sub-projects, sometimes succeed and sometimes fail.

The problem is easy to be reproduced on CI(continuous integration) SaaS 'https://codeship.com/', but not easy on CI SaaS 'https://shippable.com/'. On local PC, it is 'medium easy', no matter run 'gradle test' in CMD line or debug 'gradle test' in IDEA IDE.

Attached file 'spring-data-gremlin-2015.12.03 gradle build error on codeship.com.txt' is copied from the CI SaaS 'http://codeship.com/' when codeship.com executes 'gradle build' using 2015.12.03 source code of spring-data gremlin.

====Configuration on Saas CI http://codeship.com/ ====

By the way, the config of the project on http://codeship.com/ is:

Setup Commands:
jdk_switcher home oraclejdk8
jdk_switcher use oraclejdk8
Test Commands:
gradle clean assemble
gradle build
