Deployment Poller Crashes when trying to deploy BPEL File with errors
---------------------------------------------------------------------
Key: ODE-625
URL: https://issues.apache.org/jira/browse/ODE-625
Project: ODE
Issue Type: Bug
Components: Deployment
Affects Versions: 2.0
Environment: Tomcat/5.5 debian Linux Ode Trunk Rev. 782012
Reporter: Christian Fonden
Whenever a BPEL File that contains semantic errors is deployed, the deployment
services crashes with a FATAL Exception, thus no more Processes can be deployed
until the Ode Webapp is restarted.
This can be reproduced by performing the following steps:
1. Deploy empty ode webapp in tomcat using the trunk revision (as listed in
environment)
2. create a BPEL process that contains an error like a typo in an xpath
variable name ore something else non-syntactical.
3. The BPEL Compiler recognizes that error, which is the correct behaviour.
4. The thrown exception is propagated into the deployment service
5. The Exception is not cought in the deployment service and the deployment
poller crashes
This can be seen easily in the following ODE Log file:
