I get a NullPointerException when I try to use @OneToMany on a Map collection, example:

@OneToMany(orphanRemoval = true, cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@MapKey(name = "ref")
private Map<String, Property> properties;

java.lang.NullPointerException: null

Hi Joel,

This should actually work. Could you open a ticket in our JIRA system (https://hibernate.atlassian.net/browse/OGM) and attach a minimal test case which reproduces the issue? We can then take a close look at the cause.

Thanks for your help,

--Gunnar
