NPE during creation of a property for a specific class

[PhantomYdn]

OrientDB Version: 2.2.22

Java Version: 7+

OS: linux

It seems that OrientDB doesn't like class with name "Report". After creation of such class there are lots of interesting stuff is happening. And the only one solution: rollback to previous backup.

Creation of a new property for class "Report" or attempt to retrieve newly created class lead to the NPE in the same place.

Creation of property:

java.lang.NullPointerException

If "Report" is so specific - please make it a keyword.

@PhantomYdn just to clarify is it 2.2.2 version?

[PhantomYdn]

I'm sorry - you are right. I meant 2.2.22

[andrii0lomakin]

@PhantomYdn do you have broken database, which you are talking about? Do you have logs from this database? Preferably since the creation of a class Report? That is very important.
