Sergey Beryozkin commented on CXF-3454:
---------------------------------------
Every optional parameter has groups, so it is just very tricky to figure out
which group corresponds to a captured path var and which represents the regex
output. What are you trying to do with multiple optional params ?
thanks

> Components: JAX-RS
> Affects Versions: 2.4
> Reporter: Guillermo Castro
> Labels: jaxrs
> Attachments: URITemplateTest.java
>
>
> In JAX-RS you can define custom patterns for path variables, which allows you
> to define optional parameters that can be present or not. Currently, CXF only
> works if you only have 1 optional parameter in the @Path (see test
> "URITemplateTest.testExpressionWithNestedGroupAndTwoVars2()", but fails for
> paths with 2 or more optional parameters.
