AntPathPatternMatcher hardcoded "/" separator in variables glob

[jonenst]

If you don't use the default separator, "/" should not be special:

jshell> new AntPathMatcher("\0").extractUriTemplateVariables("tot{;}", "totoa");
$11 ==> {;=oa}

jshell> new AntPathMatcher("\0").extractUriTemplateVariables("tot{/}", "totoa");
|  Exception java.lang.IllegalStateException: Pattern "tot{/}" is not a match for "totoa"
|        at AntPathMatcher.extractUriTemplateVariables (AntPathMatcher.java:516)
|        at (#12:1)

Expected {/=oa}

note: the previous example is treated as an exact match:

jshell> new AntPathMatcher("\0").extractUriTemplateVariables("tot{/}", "tot{/}");
$19 ==> {}

See

spring-framework/spring-core/src/main/java/org/springframework/util/AntPathMatcher.java

Line 645 in 17e6cf1

private static final Pattern GLOB_PATTERN = Pattern.compile("\\?|\\*|\\{((?:\\{[^/]+?}|[^/{}]|\\\\[{}])+?)}");

there are slashes hardcoded in there
