Files locked after indexing - solrj

Question

I have the following workflow in my (web)application:
download a pdf file from an archive
index the file
delete the file
My problem is that after indexing the file, it remains locked and the delete-part throws an exception.
Here is my code-snippet for indexing the file:
try
{
ContentStreamUpdateRequest req = new ContentStreamUpdateRequest("/update/extract");
req.addFile(file, type);
req.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
NamedList<Object> result = server.request(req);
Assert.assertEquals(0, ((NamedList<?>) result.get("responseHeader")).get("status"));
}
Do I miss something?
EDIT:
I tried this way too, but with the same result...
ContentStream contentStream = null;
try
{
contentStream = new ContentStreamBase.FileStream(document);
ContentStreamUpdateRequest req = new ContentStreamUpdateRequest(UPDATE_EXTRACT_REQUEST);
// req.addFile(document, context.getProperty(FTSConstants.CONTENT_TYPE_APPLICATION_PDF));
req.addContentStream(contentStream);
req.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
NamedList<Object> result = server.request(req);
if (!((NamedList<?>) result.get("responseHeader")).get("status").equals(0))
{
throw new IDSystemException(LOG, "Document could not be indexed. Status returned: " +
((NamedList<?>) result.get("responseHeader")).get("status"));
}
}
catch (FileNotFoundException fnfe)
{
throw new IDSystemException(LOG, fnfe.getMessage(), fnfe);
}
catch (IOException ioe)
{
throw new IDSystemException(LOG, ioe.getMessage(), ioe);
}
catch (SolrServerException sse)
{
throw new IDSystemException(LOG, sse.getMessage(), sse);
}
finally
{
try
{
if(contentStream != null && contentStream.getStream() != null)
{
contentStream.getStream().close();
}
}
catch (IOException ioe)
{
throw new IDSystemException(LOG, ioe.getMessage(), ioe);
}
}

Answer 1

This seems like a bug,
a patch is proposed here
https://issues.apache.org/jira/browse/SOLR-1744
Also checkout
http://lucene.472066.n3.nabble.com/ContentStreamUpdateRequest-addFile-fails-to-close-Stream-td485429.html
you can check if the stream is not null and close it.

Answer 2

It may be due to lock acquired by file system. Instead of addFile(), you can try the following.
ContentStreamUpdateRequest req = new ContentStreamUpdateRequest("/update/extract");
ContentStreamBase.FileStream fileStream = new FileStream(file);
req.addContentStream(fileStream);
