[hibernate-dev] @org.hibernate.annotations.Index and NullPointerException in IndexOrUniqueKeySecondPass

[Vlad Mihalcea]

Hi,

You should try it with JPA @Index as well, and try to replicate it with one
of our test cases:

http://in.relation.to/2016/01/14/hibernate-jpa-test-case-template/

If it replicates, you should open a Jira issue along with your PR.

Thanks,
Vlad
