This error is generally related to missing execute permissions on jspawnhelper, a java helper program invoked by Java Development Kit to to create a new process. Please refer to Java/Oracle for more information.

Cause

Java's $JAVA_HOME/lib/jspawnhelper program may not have execute permissions.

Resolution

Check to see if $JAVA_HOME/lib/jspawnhelper has execute permissions. 

If jspawnhelper does not have execute permission, execute permission can be granted by running the below command:

chmod +x $JAVA_HOME/lib/jspawnhelper

Please refer to your OS or Java admin if needed.
