Examples of org.apache.lucene.store.LockObtainFailedException

org.apache.lucene.store.LockObtainFailedException
This exception is thrown when the write.lock could not be acquired. This happens when a writer tries to open an index that another writer already has open. @see Lock#obtain(long)

        throw new StaleReaderException("IndexReader out of date and no longer valid for delete, undelete, or setNorm operations");


      if (writeLock == null) {
        Lock writeLock = directory.makeLock(IndexWriter.WRITE_LOCK_NAME);
        if (!writeLock.obtain(IndexWriter.WRITE_LOCK_TIMEOUT)) // obtain write lock
          throw new LockObtainFailedException("Index locked for write: " + writeLock);
        this.writeLock = writeLock;


        // we have to check whether index has changed since this reader was opened.
        // if so, this reader is no longer valid for deletion
