Java-openjdk error

Dear Community,

I have latest version of java installed but for some reason I could not install shinyproxy

$ java -version
 openjdk version "15.0.2" 2021-01-19
 OpenJDK Runtime Environment Zulu15.29+15-CA (build 15.0.2+7)
 OpenJDK 64-Bit Server VM Zulu15.29+15-CA (build 15.0.2+7, mixed mode, sharing)
$ sudo rpm -i shinyproxy_2.4.3_x86_64.rpm
 error: Failed dependencies:
	java-openjdk is needed by shinyproxy-2.4.3-1.x86_64

running CentOS Stream 8
I installed java versions 15.x, 11.x, 8.x from dnf (and yum) but same error message appears.

any help will be appreciated!

thanks

reason for deletion: rpm package was built for centOS 7, installing it in centOS 8 will obviously throw error.
