Description

When using the default pattern matcher "WildcardHelper" the following action mapping behaves as if it was "*"

        <action name="*_*">
            <result>/WEB-INF/content/testmapping.jsp</result>
        </action>

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...

    @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);
    }
