Previously, only IOExceptions were caught and wrapped in a new
IOException that included the name of the nested entry that was
being read.
Following this commit, any Exception is caught and wrapped so that the
problematic entry can be identified in more failure scenarios.
Closes gh-8711
Previously, each entry in loader.path could only refer to a standard
jar file. Refering to such a jar would add all of the classes in
the root of the jar to the class path.
This commit adds support for referencing a directory within a jar file
that contains one or more nested jars. For example:
$ java -jar -Dloader.path='jar:file:./lib.jar/!BOOT-INF/lib' my.jar
This will add all of the classes in all of that jars in the
BOOT-INF/lib directory of lib.jar to the class path.
See gh-8334
The main changes are:
- Switch to `loader.properties` instead of `application.properties`
- Search for `loader.properties` in `loader.home` as well as in
the classpath
- Placeholder replacements in MANIFEST.MF (using `loader.properties`
or system/env vars)

Consider the following two URLs:
jar:file:/test.jar!/BOOT-INF/classes!/foo.txt
jar:file:/test.jar!/BOOT-INF/classes/foo.txt
They both reference the same foo.txt file in the BOOT-INF/classes
directory of test.jar, however the first URL does so via the
nested BOOT-INF/classes archive. Previously, this difference in the
URLs would lead to PathMatchingResourcePatternResolver returning two
resources for foo.txt when asked to find all resources matching the
pattern classpath*:/**/*.txt.
This commit updates our Handler that is used for jar: URLs to consider
the two URLs above to be equivalent such that url1 is equal to url2
and the two urls will produce the same hash code.
Closes gh-7449
