Description

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:
18180 [Thread-8] ERROR org.apache.ode.bpel.compiler.BpelC - null:237: error: [UndeclaredVariable] Attempt to reference undeclared variable "querytarget".
***************************************************************************************

• • • The error in the BPEL file here is a type in the variable name "querytarget". ***
