Ken McWilliams commented on WW-3985:
------------------------------------

Using **_** works fine and will resolve as expected.

> When using the default pattern matcher "WildcardHelper" the following action mapping behaves as if it was "*"
> {code:xml}
>         <action name="*_*">
>             <result>/WEB-INF/content/testmapping.jsp</result>
>         </action>
> {code}
> That is, the underscore (or any other single character) is ignored and the action will map as "*".
> I thought it was the fault of WildcardHelper so created test cases and they all passed...
> {code:java}
>     @Test
>     public void testMatch() {
>         WildcardHelper wild = new WildcardHelper();
>         HashMap<String, String> matchedPatterns = new HashMap<String, String>();
>         int[] pattern = wild.compilePattern("*b*");
>         assertEquals(wild.match(matchedPatterns, "b", pattern), true);
>         assertEquals(wild.match(matchedPatterns, "abc", pattern), true);
>         assertEquals(wild.match(matchedPatterns, "xxx", pattern), false);
>         pattern = wild.compilePattern("*_*");
>         assertEquals(wild.match(matchedPatterns, "a_a", pattern), true);
>         assertEquals(wild.match(matchedPatterns, "a", pattern), false);
>     }
> {code}
