Examples of com.persistit.exception.CorruptJournalException

com.persistit.exception.CorruptJournalException
Thrown if the journal files are corrupt. Generally it will be necessary to delete the journal to resolve this. In so doing, critical information needed to recover the state of one or more {@link com.persistit.Volume}s may be lost. @version 1.0
