[JENKINS-69205] Different name same version installation not working

If you declare two (or more) times the same JDK version using different names you can install only one of them because of the name of the directory which is written inside the zip in the cache directory.

For example:

• Name: BUILD_JDK


• Version: jdk-11.0.16+8

• Name: SONARQUBE_JDK


• Version: jdk-11.0.16+8

The root directory inside [...]/jenkins-home/caches/adoptopenjdk/WINDOWS/amd64/jdk-11.0.16+8.zip is "BUILD_JDK" (the first used), so when it needs to install SONARQUBE_JDK it simply creates an empty directory.

Raw content of original issue

If you declare two (or more) times the same JDK version using different names you can install only one of them because of the name of the directory which is written inside the zip in the cache directory.


For example:




	
Name: BUILD_JDK

	
Version: jdk-11.0.16+8





	
Name: SONARQUBE_JDK

	
Version: jdk-11.0.16+8



The root directory inside [...]/jenkins-home/caches/adoptopenjdk/WINDOWS/amd64/jdk-11.0.16+8.zip is "BUILD_JDK" (the first used), so when it needs to install SONARQUBE_JDK it simply creates an empty directory.

Start by tracing the JDK installation and cache handling described in the issue, focusing on how the cached ZIP's root directory is used. Reproduce the two differently named declarations with version jdk-11.0.16+8 on Windows amd64. Done means both names install successfully without an empty directory being created for the second installation.
