Affects: 6.1.2+ (probably since the introduction of PathPatterns)

When you use aRedirectView with an URI that contains a path variable, andPathPatterns are enabled, then the variable value is missing.

This is due to the fact that thePathPatterncodepath ofAbstractUrlHandlerMapping is callingbuildPathExposingHandler() with uriTemplateVariables parameter of null.

As a consequence noPathExposingHandlerInterceptor is added to the execution chain. The variable values are never parsed from the URI.

WhenRedirectView tries to access the variable values of the variables in the URI atreplaceUriTemplateVariables() it throws an IllegalArgumentException.

WhenAntPatterns are used instead ofPathPatterns, then the variable values are parsed and all is well.
