Issue #9511 Verify location of scanned class files

[janbartel]

Closes #9511

Check that a class file that is about to be scanned is in the correct location, skipping it if not. For example, given a class with fully qualified name com.acme.Foo that comes from jar:file://someplace/somewhere.jar!/ ensure that class is located at jar:file://someplace/somewhere.jar!/com/acme/Foo.class.
This would skip the class if it was in eg jar:file://someplace/somewhere.jar!/this/is/the/wrong/place/com/acme/Foo.class. See the original issue #9400 for more examples.

@janbartel make sure we also test for some.jar!/META-INF/versions/<ver>/com/acme/Foo.class.

[janbartel]

@sbordet there are already tests for that.

AnnotatioParser doesn't look to be related to any eeX version. could it be in a single place?

Potentially we could move it into a core jetty-annotations module, but I think that would be a separate PR.

@gregw shall we can this PR?

[joakime]

@janbartel @gregw shall we close this PR as not useful?

These changes aren't crucial.
