/**
 * Indicates that an erased entry was encountered when fetching a log entry,
 * presumably because its LSN appears in the active Btree. A checked exception
 * is used so it can be caught and handled internally in some cases.  When
 * not handled internally, it is wrapped with an EnvironmentFailureException
 * with EnvironmentFailureReason.LOG_ERASED before being propagated through
 * the public API.
