Re: Possible cause of nullPointerException in casmultiplier?

[nelson rivera]

You are absolutely right, I should not release the input CAS in my AE.
This was apparently the cause of the error. thank you very much

Re: Possible cause of nullPointerException in casmultiplier?

[Jaroslaw Cwiklik]

An input CAS should not be released in the AE (user code). The Flow
Controller should be used
to prevent a CAS from flowing downstream. UIMA-AS will try to release a CAS
in a Final Step
of processing and this may cause an error like

"The system tried to return a common analysis structure to the pool from
which it was not checked out."

Re: Possible cause of nullPointerException in casmultiplier?

[nelson rivera]

I have deployed the aggregate of asynchronous way.
 And i configure this aggregate to processing one request at the same
time(numberOfCASes=1,default), because as i commented on previous
email, in my flow: The first casmultiplier receive a annotation with
the path of a folder and creates a new child cas for each file in the
folder, the child cas
continue the flow in the other primitive annotators and at the end it
go to the second casmultipler, in the second casmultipler can or not
create new child cas, in the case of not i release the cas. I am
assuming (numberOfCASes=1,default) that until all child has finished
its processing, the aggregate not going processing other input cas of
other request, it is correct?.

Re: Possible cause of nullPointerException in casmultiplier?

[Jaroslaw Cwiklik]

Nelson, this error:

"The system tried to return a common analysis structure to the pool from
which it was not checked out."

I think this is caused if you try to release a CAS that has been previously
released. Sure you
are not trying to release it twice? I think releasing an input CAS in AE
code is not a good idea. I am assuming
you have an asynchronous aggregate (queue in front of each AE). In such
deployments, the UIMA-AS is
responsible for releasing a CAS once it reaches a Final state. Within a
synchronous aggregate I am not sure
if you are allowed to release a CAS in your code. Perhaps others can chime
in. Can you confirm which
deployment you chose for this aggregate (synch or asynch)

Re: Possible cause of nullPointerException in casmultiplier?

[nelson rivera]

I continued investigating  and according to the stacktrace and source
code of of FSIndexRepositoryImpl.ll_addFS_common() the exception is
from line 2805 , in this part

final ArrayList
indexes = this.indexArray[typeCode];
// Add fsRef to all indexes.
boolean noIndexOrOnlySetindexes = true;
for (IndexIteratorCachePair iicp :
indexes) {} //here

apparently loop on a null value, any idea of why can happen this exception?

Possible cause of nullPointerException in casmultiplier?

[nelson rivera]

I have a aggregate service that contains in the flow in this order : 1
casmultiplier, then 2 primitive annotators and at the end other
casmultiplier.
The first casmultiplier receive a annotation with the path of a folder
and creates a new child cas for each file in the folder, the child cas
continue the flow in the other primitive annotators and at the end it
go to the second casmultipler, in the second casmultipler can or not
create new child cas, in the case of not, in the  method process() i
release de cas (aJCas.release();) directly in my source code.

This aggregate service is deploys in uima-as and configure for
processing only one request at the same time .  For any reason, sometimes and of aleatorie way ,
making many requests to the service from many thread concurrent, in
the first casmultiplier in method next() after get the new cas (JCas
jcas = getEmptyJCas()) and while populate the cas , apparently some
external component in another parallel thread modifys this obtained
cas, and i get a NullPointerException adding a annotation
(jcas.addFsToIndexes(copyOfFs);) in method next().

Any idea of what may be going on?

this is the descriptor uima-as:
