AntPathMatcher regression in 4.3 RC1 [SPR-14141]

[spring-projects-issues]

Stephan Schroevers opened SPR-14141 and commented

The following test passes with version 4.2.5.RELEASE but fails with 4.3.0.RC1:

@Test
public void testPathMatcher() {
	PathMatcher matcher = new AntPathMatcher();
	assertTrue(matcher.match("https://example.com", "https://example.com"));
}

Cursory debugging indicates that the double slashes are problematic. The following test passes with both versions:

@Test
public void testPathMatcher() {
	PathMatcher matcher = new AntPathMatcher();
	assertTrue(matcher.match("https:/**/example.com", "https://example.com"));
}

This regression seems relevant because double slashes are common in patterns provided to the following methods:

• MockMvcResultMatchers#forwardedUrlPattern
• MockMvcResultMatchers#redirectedUrlPattern

I suspect this is related to #18487.
