After running the git clone https://github.com/cloudfoundry/java-buildpack, the resulting files may not contain the proper permissions.
A common reason for this *umask* value was 0027.
In some cases, the environment "umask "settings are set to a more secure value such as "0027".
Ensure that "umask" value is set to "0022" to avoid this in the future. Otherwise, ensure the permissions are set as follows:

The default installed JRE may not be Oracle. For example, if the user has OpenJDK installed, then the build pack could return this error when deploying the app. Refer to How to verify Java configuration, to determine what version of java is installed.
