Why an rpm containing an executable file with "shebang #!/usr/bin/jjs" cannot be installed?

Issue

• Rpm containing an executable file with shebang #!/usr/bin/jjs cannot be installed even if /usr/bin/jjs exists (installed by java-1.8.0-openjdk-headless).
• The problem is that java-1.8.0-openjdk-headless does not specify that it provides /usr/bin/jjs executable.
• Steps to reproduce : create spec file, build the rpm and try to install it.
• This will fail because of unsatisfied Requires: /usr/bin/jjs dependency even if the /usr/bin/jjs is installed on the system.
