This is not a huge deal, since the real problem is that the database cannot be
updated, but I thought I would share in case this can occur in other scenarios.
In my case, I have a database that I created with build 1.5m02 that I am
opening with release 1.5. According to the error message, I must not have shut
down the database properly prior to upgrade. If I attempt this a second time in
the same process I get a different exception that implies the database is still
locked. It seems to me like this operation should have been attempted inside a
try block with a finally block that performs an unlock. Here are the stack
traces:
First attempt:
