Hi, Hmm... Well, RealmBase.java:428 can no longer throw an NPE, and the resultsToArray method that replaced the previous line there seems to handle the null case correctly. However, even if this weren't the case, I'm not convinced that this error you're seeing is related to the other exception reported in this thread. The only common thing about them is that they're hard to reproduce. Your error happens during request processing, the original one reported in this thread is during server startup.
