-----------------------------------------------------------
The problem is that the properties format parsing is quite generous and rarely
throws exceptions. It usually parses something that is sometimes not correct.

I'd rather add an option to the <capture-output> tag. By default is should be
properties but one could define <Capture-output format=json> or somethign
similar in the xml

> Key: OOZIE-3248
> URL: https://issues.apache.org/jira/browse/OOZIE-3248
> Project: Oozie
> Issue Type: New Feature
> Components: action
> Affects Versions: 5.0.0
> Reporter: Andras Piros
> Priority: Major
>
> Today the user can specify to capture output of Oozie actions, and reuse that
> in EL expressions in consecutive actions of the same workflow.
> As per [*Oozie workflow functional
> specification*|https://oozie.apache.org/docs/5.0.0/WorkflowFunctionalSpec.html]:
> {quote}
> The capture-output element can be used to propagate values back into Oozie
> context, which can then be accessed via EL-functions. This needs to be
> written out as a java properties format file. The filename is obtained via a
> System property specified by the constant {{oozie.action.output.properties}}.
> {quote}
> Let the output happen in following formats:
> # first and foremost, {{java.util.Properties}} format
> # if output is not parseable, fall back to JSON parsing
> # if output is not parseable, throw an {{Exception}} like before
