I compared with both nifi 1.3.0, which is a couple commits newer than your
code, and nifi 1.1.2, which is a few commits older than your code. They are
different of course, but both are quite different than this PR's code tree:
```code
-------------
bundles-lib/src/main/java/org/apache/metron/bundles:
BundleClassLoader.java BundleThreadContextClassLoader.java
ExtensionMapping.java annotation
BundleClassLoaders.java BundleUnpacker.java
InstanceClassLoader.java bundle
BundleCloseable.java ExtensionClassInitializer.java
NotInitializedException.java util
BundleManifestEntry.java ExtensionManager.java
./annotation/behavior:
RequiresInstanceClassLoading.java
./bundle:
Bundle.java BundleCoordinate.java BundleDetails.java
./util:
BundleProperties.java FileUtilities.java HDFSFileUtilities.java
VFSClassloaderUtil.java
BundleUtil.java FileUtils.java StringUtils.java
VFSFileUtilities.java
-------------
Ignoring for now the many files at the level of nifi-framework,
nifi-nar-utils/src/main/java/org/apache/nifi: [rel/1.1.2]
./nar:
ExtensionManager.java NarClassLoader.java
NarThreadContextClassLoader.java
ExtensionMapping.java NarClassLoaders.java NarUnpacker.java
InstanceClassLoader.java NarCloseable.java
./util:
FileUtils.java
-------------
In [rel/1.3.0] this changed to:
./nar:
ExtensionMapping.java NarClassLoader.java NarManifestEntry.java
SystemBundle.java
NarBundleUtil.java NarClassLoaders.java NarUnpacker.java
./util:
FileUtils.java
-------------
which is actually quite a bit different, but same essential structure.
