A DESCRIPTION OF THE REQUEST :
If I install a HotSpot JRE or JDK on a typical Linux system (e.g. at least RedHat, Fecora, and Ubuntu), the java commands are not on the standard command path. To get them to appear on the PATH, I either need to explicitly add
 " /usr/java/bin " to PATH or use " update-alternatives " to configure each of the java commands.

JUSTIFICATION :
Setting PATH doesn't help if scripts refer to the Java commands using absolute paths.

Running 20 odd " update-alternatives --config " commands each time I install or update a Java Hotspot installation is a poor solution ...

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The installer should test to see if " alternatives " is used on the distro; e.g. check to see if " /etc/alternatives " exists. If it is, then it should use " update-alternatives --config " to configure the Java commands and utilities, and (at the user's discretion) select them as default.

Alternatively, just include a shell script in the installed " bin " directory that the user can run to do the work.
