connection.close() can throw an SQLException - if this happens, lock will not unlock:


public void close() {
if (logger.isDebugEnabled()) {
logger.debug("Closing database " + this + " and releasing lock");
}

try {
if (connection != null) {
connection.close(); // THROW HERE
connection = null;
}

if (lock != null) {
lock.unlock(); // ...unlock skipped
lock = null;
}

ConnectionCache.INSTANCE.remove(dbDir.getAbsolutePath(), mode, method);
} catch (SQLException e) {
throw Throwables.propagate(e);
}
}
