James Thomas commented on CONNECTORS-1512:
------------------------------------------
I have followed your steps (without patching) and apparently successfully built
- I got a bunch of jars in the dist directory.
These are the tarballs I used:
{code:java}
$ wget
http://apache.mirror.anlx.net/manifoldcf/apache-manifoldcf-2.10/apache-manifoldcf-2.10-src.tar.gz
$ wget
http://mirrors.ukfast.co.uk/sites/ftp.apache.org/manifoldcf/apache-manifoldcf-2.10/apache-manifoldcf-2.10-lib.tar.gz
{code}
I then tried to patch, but it's not applying:
{code:java}
$ wget

I wonder whether you're working from a revision that isn't quite the 2.10
distro? Or am I doing something obviously wrong?
I tried -a few things with patch: -merge, -fuzz etc but I'm reluctant to monkey
around with your patch too much.
P.S. I found some inconsistency in README between the src and lib distros.
Where should I report that?

> Project: ManifoldCF
> Issue Type: Bug
> Components: Documentum connector
> Affects Versions: ManifoldCF 2.8.1, ManifoldCF 2.10
> Environment: Documentum 16.4
> Manifold 2.10, using dfc jars 16.4
> Manifold server machine details (although also seen on a Windows-based MF
> 2.8.1):

> Virtualization: kvm
> Operating System: CentOS Linux 7 (Core)
> CPE OS Name: cpe:/o:centos:centos:7

> I see an NPE from the Documentum Connector when I re-run a job after deleting
> a file from the Documentum repository using the Documentum Administrator:
> {code:java}
> FATAL 2018-06-29T08:36:54,847 (Worker thread '5') - Error tossed: null
> java.lang.NullPointerException
> at
> org.apache.manifoldcf.crawler.common.DCTM.DocumentumObjectImpl.getContentSize(DocumentumObjectImpl.java:181)
> ~[?:?]
> ...
> at
> org.apache.manifoldcf.crawler.connectors.DCTM.DCTM$ProcessDocumentThread.run(DCTM.java:1399)
> ~[?:?]
> {code}
> The job then appears not to terminate in the Manifold UI. If the job is not
> aborted, the NPE will show again after restarting the Manifold server and
> Documentum Connectors.
> I expect the connectors to handle deletion of source in the repository,
> passing the appropriate status to the output connector, and not failing like
> this.
> Reproduce:
> * Configure Manifold to use Documentum Connectors to talk to a Documentum
> instance
> * Sanity check your configuration by
> ** create a directory in Documentum, D, with two files F, G
> ** create a job in Manifold to take from D and write to the file system in
> directory L
> ** run the job and observe that F, G appear in L
> * delete G from D in Documentum
> ** in Documentum Administrator, right click on G and choose Delete, then OK
> * re-run your job
> * observe that the job doesn't end
> * inspect L
> * observe that F and G are both still present
> * inspect the Manifold logs
> * observe NPE in the logs
>
> In the log file I'll attach, F and G are Book1.xlsx and Book1.xls
