> {{org.apache.struts2.views.jasperreports.ValueStackShadowMap}} (the
> {{struts2-jasperreports-plugin}}, JasperReports 6.x line) is documented as a
> {{HashMap}} whose {{containsKey}} and {{get}} fall back to
> {{ValueStack.findValue(key)}} when the key is not in the map, so that a
> report parameter declared in the {{.jasper}} can be resolved straight from
> the action. That is how {{JasperReportsResult}} hands the parameter map to
> {{JasperFillManager.fillReport}}.
> The two methods are declared as
> {code:java}public boolean containsKey(String key)
> public Object get(String key)
> {code}
> The {{HashMap}} methods they are meant to replace take {{Object}}, so these
> are overloads, not overrides (the Javadoc says "overriding HashMap
> implementation", and there is no {{@Override}}). JasperReports holds the
> parameters as a {{java.util.Map}} and calls {{get(Object)}} /
> {{containsKey(Object)}}, which resolve to the plain {{HashMap}}
> implementation. The value-stack fallback therefore never runs when called
> through JasperReports; only the entries the result puts explicitly
> ({{reportDirectory}}, {{REPORT_LOCALE}}, {{REPORT_TIME_ZONE}}, and the
> {{reportParameters}} map) reach the fill.
> The copy in the {{struts2-jasperreports7-plugin}}
> ({{org.apache.struts2.views.jasperreports7.ValueStackShadowMap}}, WW-5455)
> declares both methods with an {{Object}} parameter and {{@Override}}, so the
> two plugins behave differently for the same report and action.
> Fix: change the parameter type to {{Object}} and add {{@Override}}, matching
> the JR7 copy, with a test that fills a report whose declared parameter is
> only available as an action property.
> Note this is a behaviour change for the 6.x plugin: after the fix, a declared
> report parameter that the action exposes as a property but does not put in
> {{reportParameters}} starts being resolved from the value stack, as the
> Javadoc has always claimed. Worth a line in the version notes.
> Found while triaging WW-3245; no security impact (the fallback keys are the
> parameter names compiled into the developer's {{.jasper}}, not request data).
