Update `PropertiesLauncher` so that classes can be loaded outside of
`BOOT-INF/classes`. You can use a subdirectory, or the root directory
of an external jar (but not the parent archive to avoid issues
with agents and awkward delegation models).
Fixes gh-8480
Closes gh-8486
Previously, jars (either top-level or nested) in Zip64 format were
treated as normal jar files. This would lead to a failure later on
when an attempt was made to read an entry from the file.
This commit updates the loader to fail fast when it encounters a
Zip64 jar file. Such files are identified by the number of entries
in the central directory end record being 0xFFFF.
Closes gh-8735
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)
