JRE8-WN-000020 - Oracle JRE 8 deployment.config file must contain proper keys and values - deployment.system.config.mandatory

Details

The deployment.config configuration file contains two keys.



The 'deployment.properties' key includes the path of the 'deployment.properties' file and the 'deployment.properties.mandatory' key contains either a TRUE or FALSE value.



If the path specified to 'deployment.properties' does not lead to a 'deployment.properties' file, the value of the 'deployment.system.config.mandatory' key determines how JRE will handle the situation.



If the value of the 'deployment.system.config.mandatory' key is TRUE and if the path to the 'deployment.properties' file is invalid, the JRE will not allow Java applications to run. This is the desired behavior.


Solution

Navigate to the 'deployment.config' file for JRE.

Add the key 'deployment.system.config=' to the 'deployment.config' file. The following is an example:
'deployment.system.config=file:///C:/Windows/Java/Deployment/deployment.properties'. Note the use of forward slashes.

Add the key 'deployment.system.config.mandatory=true' to the 'deployment.config' file.
