Changed child classes to use this shared object
Changed some classes that previously extended ExecutionContextUserSupport
to rather use the same common parent class as everything else.
Changes all for issue BATCH-1966
* Ensure bundlor is available and remove from sample
* Tidy dependencies in some poms
* Update some template.mf dependencies
* Add .travis.yml for automated builds independent of bamboo
- MapJobRegistry no longer implements StepRegistry
- DefaultJobLoader updates the stepRegistry when it is available
- Added more tests to cover the cases where the step registry is not available
- Added a simple MapStepRegistry that keeps track of the step in a simple map per job
- MapJobRegistry implements StepRegistry as well using the delegate pattern
- DefaultJobLoader makes sure to initialize both registries now. Auto-detects that the JobRegistry implements StepRegistry
- JobSupport now implements StepLocator so that such job can be loaded by the DefaultJobLoader
- Also registering any "detached" step available for a particular job to that job if that wasn't done yet. Since a partition handler may link to any step by name, the step registry must be filled with any step that are available in the context of a job. If each job is located in its own application context, this is just fine. If more than one job is defined in the same context, the step registry may be able to return a step that is not related to that job but it shouldn't hurt as this happens only if a component is explicitly asking to execute a step by name for a particular job.
* Updated the job-repository tag to allow for a serializer and deserializer to be injected
* Updated the XStreamExecutionContextStringSerializer to implement Serializer and Deserializer
* Replaced the ExecutionContextStringSerializer with the ExecutionContextSerializer interface
* Updated the XSD and parser to accept the injection of an implementation of the ExecutionContextSerializer from the job-repository tag
* Updated the JdbcExecutionContextDao to use injected ExecutionContextSerializer implementation
