spring-core 5.1.5.RELEASE AntPathMatcher.isPattern have bug?

I both used springframework/spring-core 5.0.5.RELEASE and spring-core 5.1.5.RELEASE.

I found AntPathMatcher.isPattern method was modified which caused the following exception.

In 5.0.5.RELEASE, I can successful get Resources by:

PathMatchingResourcePatternResolver().getResources("

classpath:com/xiao/mapper/common/*.xml")

I used "evaluate" found "getPathMatcher().isPattern(locationPattern.substring(prefixEnd))" returned false, so it processed to "return new Resource[]

{getResourceLoader().getResource(locationPattern)}

;". Then i get the right resources.

But, in 5.1.5.RELEASE, it doesn't work. "getPathMatcher().isPattern(locationPattern.substring(prefixEnd))" returned true, and it processed to "this.findPathMatchingResources(locationPattern)", finally, it returned empty resources.

I am confused about this. HOPE for your replay.

There are some screenshots, hope may help.

ScreenShot 1, it returned false:

sScreenShot 2, I got right resources:

SScreenShot 3, I used 5.1.5.RELEASE, it returned true:

SScreenShot 4, in 5.1.5.RELEASE, I got empty resources:
