Information from RuntimeExceptions escapes Axis2 error handling mechanism
-------------------------------------------------------------------------
Key: AXIS2-5245
URL: https://issues.apache.org/jira/browse/AXIS2-5245
Project: Axis2
Issue Type: Bug
Components: kernel
Affects Versions: 1.5.2
Reporter: James Grahn
RuntimeExceptions result in abnormal behavior from Axis2.
When an AxisFault is thrown, generally the fault is recorded in the message
context, then a FaultFlow is invoked. Handlers operating in the FaultFlow
context may then discover the fault through examination of the message contexts
attached to its operation context.
If a runtime exception is thrown, however, the exception is lost, even though
the FaultFlow is properly invoked. FaultFlow Handlers can no longer discover
the exception which caused their invocation.
I recognize that best practice would include packaging every thrown exception
in an AxisFault or AxisFault derivative. However, given that Axis2 does
attempt to respond sensibly to RuntimeExceptions, I do not believe that having
a "silent" FaultFlow invocation with no access to the originating exception is
proper behavior.
The fix for this issue would involve (minimally) adding a catch clause to
various methods in AxisEngine to set the failure reason on the message context
when a runtime exception is intercepted, then rethrowing the original
exception. Fault handlers would then be able to recover information from the
originating exception.
