What version of the product are you using? On what operating system?
Irrelevant.

Please provide any additional information below.

displayableUnboxed.getType().equals(AlertType.INFO);
When Alert has no type, getType() returns null:
null.equals(AlertType.INFO) raises exception.

Has been fixed in a more generic way (not modifying displayableUnboxed null 
type)
