Java expiry information

Hi,

Code:
I have a requirement to check the expiry date of Java software installed in  linux servers.

We are using the below Java

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

I am not sure whether we can get that but after few research what  found is

a. Go to <java_home>\bin
b. Run jarsigner -verify -verbose -certs <jarfilename>.jar 

As per the above steps gave
echo $JAVA_HOME which resulted in 
/usr/lib/jvm/java



The problem is there are no .jar file in  the above path.Is there a way to get the expiry date, if so how to get.

Thanks in advance.

NAME
airport2-ipinspector - WAN monitoring utility for the Apple AirPort Extreme Base Station ("Snow") SYNOPSIS
airport2-ipinspector DESCRIPTION
airport2-ipinspector monitors the WAN interface of the base station and sends an email notification whenever the external (WAN) IP address of the base station changes. OPTIONS
airport2-ipinspector accepts no command-line options. airport2-ipinspector is a wrapper script around the IPInspector.jar jar file located in /usr/share/java/airport-utils. You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ- ment variable to 1 to get the debug output from the wrapper script. ENVIRONMENT VARIABLES
DEBUG Set this variable to 1 to get the debug output from the wrapper script. JAVACMD The full path to the Java Virtual Machine to use. By default, the wrapper uses JAVACMD; if it is not set, it looks for JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can be configured using the Debian alternatives system (see update-alternatives(8)). JAVA_HOME The full path where your JDK/JRE is installed. JAVA_BINDIR The full path to the directory where the java executable is located. JAVA_ARGS Extra command-line arguments to be passed to the Java Virtual Machine. AUTHOR
