hi, I think I bumped into a similar bug. I have a multithreaded app; an instance of some class is updated; then it is loaded and an NPE is thrown by H2. I use #169, Windows 7, NTFS.
I cannot provide a test case at the moment; nor can I reproduce it again. Could you please look what can be wrong? Thank you.
