A DESCRIPTION OF THE PROBLEM :
Java command line tools are missing or seem to point to the wrong versions.
This might be because I have had earlier Apple releases installed since some seem to point to old Apple install files...

which jdeps
/usr/bin/jdeps

ls -l /usr/bin/jdeps
lrwxr-xr-x 1 root wheel 75 Jun 4 20:48 /usr/bin/jdeps -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/jdeps

which I believe goes back to old Apple and not Oracle but possibly Oracle does still use this Framework for installations?

Sizes seem to differ between what shows in the Framework and what shows at the install location.

For java.

ls -l /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
-rwxr-xr-x 1 root wheel 58288 Apr 28 2017 /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

For installed...

ls -l `/usr/libexec/java_home`/bin/java
-rwxrwxr-x 1 root wheel 81200 Aug 2 23:17 /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/bin/java

However, versions still seem to be correct...

For installed...

/usr/libexec/java_home
/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home

`/usr/libexec/java_home`/bin/java -version
java version "9"
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)

For Framework...

/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java -version
java version "9"
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)

So whatever is pointed to by the Framework might be correct despite the size difference.
For the other tools it is harder to be sure the version matches because they just show as version 9 with no build information.

Also, the jlink command doesn't seem to have anything pointing to it. Again for jdeps...

echo `which jdeps` is here
/usr/bin/jdeps is here

but for jlink...

echo `which jlink` is here
is here

Nothing is here.

So.
1). Is the java Framework mechanism still what should be used for command line tools?

2). If it is does it always point to correct versions?

3). There is nothing pointing to the jlink command line tool.




STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Install java 9

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Command line tools present and correct versions in supported locations.

ACTUAL -
The command line tools are indirectly through a possibly Apple legacy java Framework.

The jlink although present in the installed JRE seems to be missing.

CUSTOMER SUBMITTED WORKAROUND :
For jlink for now I added an alias in my .bash_profile. I didn't want to mess with symbolic links which might interfere with a possible more permanent later fix.
