Is camunda compatible with Java EE 7?
Raul Ivan Garcia Valdivia
Frank Langelage
regarding the question about compatibility with Java EE 7 I would answer yes.
Regarding compatibility with WildFly 9 the answer is no.
The Camunda module for WildFly 8, which is available, uses the deprecated jboss threads subsystem. The Camunda guide tells you how you add the jboss threads module to your config file (e.g. standalone-full.xml).
With WildFly 9 this subsystem is no longer available at all and therefore cannot be added anymore.
My fork of Camunda BPM at https://github.com/langfr/camunda-bpm-platform contains WildFly 9 support. But it's a current Camunda 7.4.0-SNAPSHOT (work in progress) enhanced with the WildFly 9 support and support for IBM Informix.
As you say you're starting the case that it is a SNAPSHOT should be no problem for you. It's the version I'm using in my development environment too.
You might checkout the master branch and build it yourself (the wildfly9 / wildfly9+ branches cannot be build anymore).
If you not like to build it yourself, please comeback. I can drop a camunda-bpm-wildfly9-7.4.0-SNAPSHOT.zip file for you somewhere.

Hallo Frank,
I am using your Fork to use Camunda with Wildfly 9 and it is working fine as long as I do not try to do asynchronous steps. The moment I switch part of the process to asynchronous I receive a NullPointerException:
ERROR [org.camunda.bpm.engine.context] (default task-2) ENGINE-16004 Exception while closing command context: ENGINE-11001 NullPointerException while registering synchronization: org.camunda.bpm.engine.ProcessEngineException: ENGINE-11001 NullPointerException while registering synchronization

Do you have any Idea as to the cause?

sorry for my late reply.
Although I have most tasks end events marked as "Asynchronous before" I did not see such problem when using this build.
But I'm using this build in a Wildfly 10 server which might make a difference, but I doubt that this is the cause.
As far as I saw from your stacktrace, the exception is already thrown when deploying the process definition:
at org.camunda.bpm.engine.impl.RuntimeServiceImpl.startProcessInstanceByKey(RuntimeServiceImpl.java:78)
Regards, Frank

I can not post the entire process here, as it contains some customer related details.
Here is the part in question:
<bpmn2:sequenceFlow id="SequenceFlow_16" name="" sourceRef="buildFioTask" targetRef="sendSuccessResponse" />
<bpmn2:serviceTask id="sendSuccessResponse" name="send Success Response" camunda:expression="${fioNewResponseBuilder.buildGoodResponse(execution)}">
<bpmn2:incoming>SequenceFlow_16</bpmn2:incoming>
<bpmn2:outgoing>SequenceFlow_50</bpmn2:outgoing>
</bpmn2:serviceTask>
<bpmn2:sequenceFlow id="SequenceFlow_50" name="" sourceRef="sendSuccessResponse" targetRef="SetTaskStateNew" />
<bpmn2:serviceTask id="SetTaskStateNew" name="set FIO Task State to New" camunda:asyncBefore="true" camunda:expression="${fioNewProcessor.setTaskState(execution, 10)}">
<bpmn2:incoming>SequenceFlow_50</bpmn2:incoming>
<bpmn2:outgoing>SequenceFlow_7</bpmn2:outgoing>
</bpmn2:serviceTask>
<bpmn2:sequenceFlow id="SequenceFlow_7" name="" sourceRef="SetTaskStateNew" targetRef="sendTaskNotificationNew" />
<bpmn2:serviceTask id="sendTaskNotificationNew" name="send Task Notification" camunda:expression="${fioNewProcessor.basicFioNotification(execution)}">
<bpmn2:incoming>SequenceFlow_7</bpmn2:incoming>
<bpmn2:outgoing>SequenceFlow_8</bpmn2:outgoing>
</bpmn2:serviceTask>
If I remove the camunda:asyncBefore it works, with it the Nullpointer is thrown. The goal would be that the response is returned to the client (webservice request) before the Notifications are sent.
To the process on a high level is Receive WebService Call -> Start Camunda Process -> Use ServiceTasks to calculate Answer -> Return Synchronous WebService Answer -> Send some Notifications to other Systems.
If this snippet is not enough I can try to reproduce the error with a generic TestProcess.
Thanks for your time
