* Windows: allow absolute file paths without file:/// prefix
* All: only add nested archives (not directories), so loader.path=lib/*
behaves the same as -classpath=lib/* (except for adding zip files)
Fixes gh-1352
The ExplodedArchive would erroneously always attempt to filter
its contents (and thereby shield them from a classloader that wrapped
it) even if they haven't been explicitly provided.
See gh-1352
Use Java 7 `registerAsParallelCapable` and `getClassLoadingLock` methods
when possible. This should improve performance when running on JDK 7+
whilst still remaining JDK 6 compatible.
Closes gh-1284
Fix 'fat jar' support for windows to correctly deal with URL and path
slash issues. The root cause of the original problem was caused by JAR
URLs not including a root slash (ie `file:C:/Users` vs `file:/C:/Users`)
Fixes gh-1145
Update ExecutableArchiveLauncher so that `-cp` URLs are not added
when they are already contained as nested JARs. This prevents a
SecurityException "signer information does not match error" when using
signed jars. The root cause of the issue was that the primary JAR file
was on the default classpath with the URL "file:....jar" and in the
main URL set as "jar:file:....jar". It is now filtered so that only
the "jar:" variant is added.
Fixes gh-1134
Update the executable JAR code to automatically unpack any entries
which include an entry comment starting `UNPACK:` to the temp folder.
The existing Maven and Gradle plugins have been updated with new
configuration options and the `spring-boot-tools` project has been
updated to write the appropriate entry comment based on a flag passed
in via the `Library` class.
This support has been added to allow libraries such a JRuby (which
assumes that `jruby-complete.jar` is always accessible as file) to work
with Spring Boot executable jars.
Fixes gh-1070
Update JarURLConnection to allow the resolution of items within a nested
jar, even if the jarFile passed to the connection is several levels up.
This prevent a connection from incorrectly resolving an entry against
the wrong jar file.
See gh-1070
Tweak 'fat jar' handling to generally improve performance:
- Allow JarURLConnection to throw a static FileNotFoundException when
loading classes. This exception is thrown many times when attempting
to load a class and is silently swallowed so there is no point in
providing the entry name.
- Expose JarFile.getJarEntryData(AsciiBytes) and store AsciiBytes in
the JarURLConnection. Previously AsciiBytes were created, discarded
then created again.
- Use EMPTY_JAR_URL for the JarURLConnection super constructor. The URL
is never actually used so we can improve performance by using a
constant.
- Extract JarEntryName for possible caching. The jar entry name
extracted from the URL is now contained in an inner JarEntryName
class. This could be cached if necessary (although currently it is
not because no perceivable performance benefit was observed)
Fixes gh-1119
Update JarFile to reuse the previously parsed entries when creating
filtered jars. This saves needing to re-scan the underlying file to
recreate a subset of entries.
See gh-1119
Drop JarEntryFilter arguments from the JarFile constructor and the
getNestedJarFile methods. Filtered JarFiles can still be obtained by
using the getFilteredJarFile() method.
This helps simplify the code a little and will make it easier to add
caching.
See gh-1119
Update `spring-boot-loader` ZIP processing code to support prefixed
bytes within the fat jar. This technique allows a bash script to be
embedded at the start of the JAR whilst still allowing `java -jar`
execution.
Fixes gh-1073
Unify the versions used in integration tests launched by the
maven-invoker-plugin. Allows for already cached local copies to be
used, hopefully speeding up the build.

ExecutableArchiveLauncher creates a ClassLoader that is used by the
Launcher to load an application’s classes. During the creation of this
ClassLoader URLs from another ClassLoader are copied over. This was
resulting in Java agents that are added to the system class loader
via the -javaagent launch option being available on both the system
class loader and the created class loader. Java agents are intended to
always be loaded by the system class loader. Making them available on
another class loader breaks this model.
This commit updates ExecutableArchiveLauncher so that it skips the URLs
of any Java agents (found by examining the JVM’s input arguments) when
copying URLs over to the new classloader, thereby ensuring that Java
agents are only ever loaded by the system class loader.
