public class InconsistentDatabaseStateException

extends IOException

When changes are made to a RecordFile database (or any one object that uses a RandomAccessDatabaseStream as its underlying IO stream) these changes are done "safely". That is to say, changes are done via a idempotent commit operation that is stored within the file. Should the application abort or crash before the commit operation is completely done, the RandomAccessDatabaseStream will attempt to re-apply the commit operation the next time the database is opened.

However if the database is opened in read-only mode, and the Database cannot determine a way to re-open it in "rw" mode to re-apply the commit, then this exception will be thrown.

The correct way to handle this exception is to explicitly re-open the database in "rw" mode - to allow the commit to be applied, and then close it and re-open it in "r" mode as originally intended.

If you absolutely cannot open the database in "rw" mode then you must open it in "r" mode specifying that the commit operation should be ignored.
