For a variety of reasons, I have a nested bean archive available in my jar file under FOOBAR/classes. This means there is a FOOBAR/classes/META-INF/beans.xml file in there.

Weld SE properly finds the beans.xml there, but when the FileSystemBeanArchiveHandler class goes to do things with it, it is skipped due to a trailing slash equality comparison issue.

In FileSystemBeanArchiveHandler.java, line 125 and following, it reads:

       try (ZipFile zip = new ZipFile(file)) {

            Enumeration<? extends ZipEntry> entries = zip.entries();

            while (entries.hasMoreElements()) {

                ZipEntry zipEntry = entries.nextElement();

                if (zipEntry.getName().equals(nestedEntryName)) { // XXXX <--- this is the problem

At line 133 (marked with // XXXX above), the zipEntry's name will (in my case) end with a trailing slash, whereas the nestedEntryName will not end with a trailing slash. This means that only nested jar files, not nested archive directory roots, can be detected.
