Description
ADDITIONAL SYSTEM INFORMATION :
macOS Catalina 10.15.7

openjdk version "15.0.2" 2021-01-19
OpenJDK Runtime Environment (build 15.0.2+7-27)
OpenJDK 64-Bit Server VM (build 15.0.2+7-27, mixed mode, sharing)

WARNING: Using incubator modules: jdk.incubator.jpackage
15.0.2

A DESCRIPTION OF THE PROBLEM :
Previously on OS X java.library.path would include paths internal to the application. 
some.app/Contents/MacOS and some.app/Contents/app
MacOS could probably be eliminated as 'app' is the jpackage supported way to include user files.
However, these paths no longer appear included and instead external paths are.


REGRESSION : Last worked in version 14

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start an application with needed dylib's in the input directory to go to the app directory.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The native library will successfully load based on the java.library.path setting.
ACTUAL -
Exception in thread "main" java.lang.UnsatisfiedLinkError: no hp in java.library.path: /opt/ooRexx/lib/ooRexx:/Users/mjh/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.
	at java.base/java.lang.ClassLoader.loadLibrary(Unknown Source)
	at java.base/java.lang.Runtime.loadLibrary0(Unknown Source)
	at java.base/java.lang.System.loadLibrary(Unknown Source)
	at us.hall.osx.LogOut.<clinit>(LogOut.java:9)
	at us.hall.hp.common.LoaderLaunchStub.main(LoaderLaunchStub.java:59)

The load fails because java.library.path no longer seems to include the internal 'app' directory.

CUSTOMER SUBMITTED WORKAROUND :
Setting the java.library.path as a startup option like...
-Djava.library.path=$APPDIR

FREQUENCY : always

Reply from the submitter ========================= It appears to work correctly at this version.

Given that jpackage doesn���t use it the MacOS directory could still probably be removed. I���m not seeing how compatibility would be a concern. But yes, a fix.
