[HV-818] ArrayIndexOutOfBoundsException in ReflectionHelper

I'm experiencing problems using Hibernate Validator 5.0.1.Final.

I have some static factory methods with different parameters that raise an ArrayIndexOutOfBoundsException on application deploy.

I got the issue and created a test, whilst I already 'patched' a snapshot version to workaround my problem.

PS: I'm not able to follow the contributing guidelines because I can't signup in Hibernate JIRA to create a issue, maybe it's a Atlassian problem.
