How can I reinstall java with ansible using the DNF command - linux

Question

I've been trying to remove some java files and reinstall them to prevent a bug on rocky linux but I have troubles doing so while using the DNF module.
My problem might be from me using the shell command "rpm -qa | grep java" to gather the files that I need to reinstall but I just can't tell.
Here's my code:
---
- name: Rocky | Java reinstall to prevent bugs
hosts: "fakeHost"
gather_facts: false
become: true
tasks:
#Ping the server
- name: Test reachability
ping:
#Check if the path exist
- name: Check java file path
stat:
path: /usr/lib/jvm/java
register: dir_name
#Report if the dir exists
- name: Report if the dir exists
debug:
msg: "The directory exists"
when:
- dir_name.stat.exists
#Load up all the java file that the machine has
- name: grep all java file
shell: "rpm -qa | grep java"
args:
warn: false #prevent false change
register: java_files
when:
- dir_name.stat.exists
#Display all the java files of the machine
- name: Show all java java_files
debug:
msg: "{{ item }}"
loop:
- "{{ java_files.stdout_lines }}"
when:
- dir_name.stat.exists
#Uninstall each java file with the DNF command
- name: Uninstall all the java files
dnf:
name: "{{ item }}"
state: absent
autoremove: no
loop:
- "{{ java_files.stdout_lines }}"
when:
- dir_name.stat.exists
#Install each java file with the DNF command
- name: Install all the java files
dnf:
name: "{{ item }}"
state: present
loop:
- "{{ java_files.stdout_lines }}"
when:
- dir_name.stat.exists
