The Digital Signature of a message is invalid - application deployed in tomcat

One of the form in application shows the error "The Digital signature of a message is invalid"

Issue: 

Above mentioned error message is displayed in the browser. However, Errors are not logged in the logs.

Solution:

Check the Java path of the application. In some cases, When there is a OS reboot performed, The JAVA_HOME and JRE_HOME will be nullified. Due to this the JAVA_HOME will be taken as default OS path.

Change the JAVA_HOME path to the one that is compatible with the tomcat service that is currently running.
