Environment

forum: https://www.cuba-platform.com/discuss/t/uberjar-creates-app-jar-with-0-byte-manifest-mf/12349/3

reproduced by me on Ubuntu 20.04, OpenJDK 8 1.8.0_252 (openjdk-8-jdk package).

Platform version: 7.2.3, 7.2.4
Gradle version: 5.6.4

Description of the bug or enhancement

Download https://github.com/cuba-platform/sample-session-planner sample
Switch project SDK and Gradle SDK to java 8.

Create UberJar task with Studio:

task buildUberJar(type: CubaUberJarBuilding) {
singleJar = true
appProperties = ['cuba.automaticDatabaseUpdate': true]
}

CUBA -> Deployment -> Build UberJAR
Run created jar file:
```
$ java -jar app.jar 
Error: Unable to access jarfile app.jar
```
If you open the jar file, you will see that manifest.mf is empty.

Not reproduced with openjdk-11.

I'm having the same issue with Platform 6.10.17. Could it be related?
