I have opened HHH-8899 https://hibernate.atlassian.net/browse/HHH-8899 . However, since no one looked at it there, I decided to open this one under tools.

If I have java8 lambda syntax anywhere in my code (not just my entities), the following line of code fails:

EntityManagerFactory trelair = Persistence.createEntityManagerFactory("puName", config.getProperties());

Here is the stack trace
