[MSHADE-356] Include filters with minimizeJar do not work with single class file

**[Dan Ziemba](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=zman0900)** opened **[MSHADE-356](https://issues.apache.org/jira/browse/MSHADE-356?redirect=false)** and commented

When using the minimizeJar feature, it is possible to explicitly include some classes that would have otherwise been excluded: MSHADE-111.  The documentation shows a filter like this:

```xml

foo:bar
false

foo/Bar.class

```

This does not seem to actually work.  If class Bar is not actually referenced, it is still removed from the shaded jar. 

Using a wildcard include pattern like "`foo/\*`" or "`foo/Bar\*`" will work, but including the period like "`foo/Bar.\*foo/Bar`".

It seems that the include pattern actually matches on the class name, not the class file name.  Is this a documentation bug, or a bug with the minimizeJar feature?

**Affects:** 3.2.2

Start by reproducing the minimizeJar behavior with the XML filter examples in this issue, comparing a single .class include with wildcard patterns. Trace where include patterns are matched and determine whether class-file extensions are supported. Done when the behavior matches the documented filter syntax or the documentation clearly describes the supported pattern.
