------------------------------------

[~nidhikv] I've tried to quickly reproduce this issue.  Is that trailing space intentional in your example? {{"/a/b/* "}}

> Hi,
>         Not sure if this is a bug but there appears to be a difference in the way regex patterns with trailing spaces are matched in shiro-core. This behavior seems to have changed between v1.7.0 and v1.7.1.
> Steps to replicate:
> RegexTest.java:
> {code:java}
> import org.apache.shiro.util.AntPathMatcher;
> public class RegexTest {
>   public static void main(String[] args)
>   {
>     AntPathMatcher matcher = new AntPathMatcher();
>     System.out.println("Matching ====" + "/a/b/* " + "==== with ====" + "/a/b/c" + "====");
>     System.out.println("RESULT: " + matcher.match("/a/b/* ", "/a/b/c"));
>   }
> }
> {code}
>  
>  
> Output with v1.7.0:
> $ java -cp "shiro-core-1.7.0.jar;." RegexTest
>  Matching ====/a/b/* ==== with ====/a/b/c====
>  RESULT: *true*
>  
> Output with v1.7.1:
> $ java -cp "shiro-core-1.7.1.jar;." RegexTest
>  Matching ====/a/b/* ==== with ====/a/b/c====
>  RESULT: *false*
>  
> Can you please let me know if this change was an intentional fix to an existing bug or a new bug that got introduced?
> Is there any flag to retain the prior behavior?
>  
> -Thanks
>
