Hi, all
Recently, we need to support MSSQL2016. After running some test in one
cluster environment, we meet following dead lock issue. I have two questions
1. Based on what I know, synchronizing repository doesn't need acquire
write lock, so why deadlock happened
2. The exception handling looks not good on
SharedItemStateManager.externalUpdate. In my case, some unexpected
exception, i.e. UndeclaredThrowableException, is throw out, that's because
some reflection is used when executing sql. As this non-ItemStateException
is thrown, SharedItemStateManager will not release the global writer lock,
make repository in this VM not working.
