Re: NullPointerException when RunRemoteAsyncAE tries to unload (UIMA AS and UIMA C++)

[Jaroslaw Cwiklik]

David, I've deployed uima-as 2.9.0-SNAPSHOT here:

https://repository.apache.org/content/repositories/snapshots/org/apache/uima/uima-as/2.9.0-SNAPSHOT/

there is a binary tarball (tar.gz) in there.

This is a trunk level uima-as code for the upcoming 2.9.0 uima-as release.
It has not been thoroughly
tested or vetted yet.  It has some fixes and improvements since 2.8.1. It
includes a new AMQ broker
version 5.14.0. It also has a fix for the problem you've reported.

Re: Broken conections after ACTIVEMQ restart

[Jaroslaw Cwiklik]

Can you install AMQ broker 5.14.0 to see if this is related to broker
issues.

Thanks for the quick response

Yes, it occurs every time, at the same line in RunRemoteAsyncAE and

Re: Broken conections after ACTIVEMQ restart

[nelson rivera]

just like that, the parent CAS comes back but the child CAS doesnt.

And the child CAS if processed, because  the  uima-as log shows the
lines of the other annotators primitive of the flow processing the
child CAS, but not comes back to UIMA-AS client.

uima-as log only shows
"Jms Listener Failed. Endpoint:
temp-queue://ID:localhsot-H81-M1-33610-1474481197190-1:1:1 Managed By:
tcp://localhost:61616 Reason: javax.jms.JMSException:
java.io.EOFException" 
ADVERTENCIA: Jms Listener Failed. Endpoint: XClusterAnalyzerAggregate
Managed By: tcp://localhost:61616 Reason:
javax.jms.IllegalStateException: The Consumer is closed..

The CAS is send to service after restart the Broker, and how say
parent CAS comes back but the child CAS doesnt. And if i try quiesce
the Aggregate Service console shows : "Quiescing UIMA-AS Service.
Remaining Number of CASes to Process:1".  I suppose that is the child
CAS.

the client if can send more CASes to the service, but not receive
response, for each CAS send after the one CAS that was send after
restart broker (for which  parent CAS comes back but the child CAS
doesnt)  not comes back parent CAS or child CAS.

More specific:
scenario 1:
1- Start Broker and UIMA-AS aggregate service. Everything is fine.

2- Restart Broker (without restart the service).  UIMA-AS log show  :
"Jms Listener Failed." 
3- Client sends a CAS to UIMA-AS aggregate service.(The parent CAS
comes back but the child CAS doesnt, to the uima-as client.)
If i try quiesce the Aggregate Service console shows : "Quiescing
UIMA-AS Service. Remaining Number of CASes to Process:1"

scenario 2:
1- Start Broker and UIMA-AS aggregate service. Everything is fine.

2- Restart Broker (without restart the service).  UIMA-AS log show  :
"Jms Listener Failed." 
3- Client sends a CAS to UIMA-AS aggregate service.(The parent CAS
comes back but the child CAS doesnt, to the uima-as client)
4- Client  sends another CAS to UIMA-AS aggregate service.(not comes
back parent CAS or child CAS , to the uima-as client)
5- Client  sends another CAS to UIMA-AS aggregate service.(not comes
back parent CAS or child CAS , to the uima-as client)
 If i try quiesce the Aggregate Service  console shows: "Quiescing
UIMA-AS Service. Remaining Number of CASes to Process:5"

Re: NullPointerException when RunRemoteAsyncAE tries to unload (UIMA AS and UIMA C++)

[Jaroslaw Cwiklik]

This warning

WARN  Transport  - Transport Connection to: tcp://
127.0.0.1:56261 failed: java.io.EOFException

is from brokers log or console I suspect. It just means that the broker
lost a connection to a client. Looks like the client
went away without closing a connection. This is probably a side-effect of
NPE.

Is the NPE repeatable? Does it happen each time you run this test? Looking
for a hint if there is a race
condition in the UIMA-AS code.

Re: Broken conections after ACTIVEMQ restart

[Jaroslaw Cwiklik]

When a parent CAS comes back (after broker is restored), can the client
send more CASes to the service and receive responses? I am trying to
determine what the real problem is here.

1) JMS Listener not recovering connection
2) UIMA-AS is not handling CAS reply failures when broker connection is
stale
