Update JAR `Handler` logic so that the existing `jarFile` is only used
if the requested URL starts with the same path. Prior to this commit it
was possible to construct a URL with another URL as context. This could
mean that the `handler` was shared and the already resolved `jarFile`
contained in the handler wasn't necessarily suitable.
Fixes gh-12483
This commit updates all `toLowerCase()` and `toUpperCase` invocations to
use the variant that takes a `Locale` to avoid locale-specific side
effect.
Closes gh-12213
Previously when Handler was creating a URL from a context URL and a
spec, any occurrances of /../ or /./ in the spec would be left as-is.
This differed from the JDK's Handler implementation which normalizes
the URL by modifying the path to remove any occurrences of /../ or
/./
This commit updates our Handler implementation to align it with the
JDK's. Tests have been added to assert that, given the same inputs,
the two Handler classes produce the same output.
Closes gh-9917
Update nested JAR support to only obtain JUL loggers when absolutely
necessary and to defensively deal with failures.
Prior to this commit it was not possible to override
`java.util.logging.manager` to use a nested JAR as the logger
implementation.
Fixes gh-9848
Calling launch of PropertiesLauncherTests sets the thread context
class loader to an instance of LaunchedURLClassLoader. To avoid this
class loader being used beyond the scope of the test and launcher
that created it, this commit updates PropertiesLauncherTests to
capture the TCCL before each test and restore it after each test.
Closes gh-9378
This commit makes sure the integration tests use the same versions as
the one managed by `spring-boot-dependencies` (including Maven plugins).
Closes gh-8947
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.
