In for example, the following:
{{ hostvars[host]['java_one']['stderr_lines'] | reject('contains', 'OpenJDK') }}
or
{{ hostvars[host]['java_one']['stderr_lines'] | select('contains', 'Java(TM)') }}
how can i add a second value to select or reject? I want the action to take place if "OpenJDK" OR "Java(TM)'" is found.

https://docs.ansible.com/ansible/latest/user_guide/playbooks_tests.html#testing-if-a-list-contains-a-value
you might want to use "Testing strings"
https://docs.ansible.com/ansible/latest/user_guide/playbooks_tests.html#testing-strings
For example, use *search* and test the list is not empty to take
action if "OpenJDK" OR "Java(TM)" is found
when: list_of_lines|
select('search', 'OpenJDK|Java\(TM\)')|
list|
length > 0

Ok. Here's the entire playbook:
---
- hosts: all
gather_facts: false
become: yes
become_user: root
become_method: su
tasks:
- name: list java version
command: java -version
register: java_one
- name: print output
debug:
msg: "{{ java_one.stderr }}"
- local_action:
module: copy
content: |
{% for host in ansible_play_hosts %}
{{ host }}
{{ hostvars[host]['java_one']['stderr'] | select('contains', 'Java(TM)') }}
- hosts: all
gather_facts: false
become: yes
become_user: root
become_method: su
tasks:
- name: list java version
command: java -version
register: java_one
- name: print output
debug:
msg: "{{ java_one.stderr }}"
- local_action:
module: copy
content: |
{% for host in ansible_play_hosts %}
{{ host }}
{{ hostvars[host]['java_one']['stderr'] | select('contains', 'Java(TM)') }}
{% endfor %}
dest: "/Users/dyioulos/Documents/prodjava.txt"
run_once: yes
dest: "/Users/dyioulos/Documents/prodjava.txt"
run_once: yes
Assuming I remove " | select('contains', 'Java(TM)')", where would I plug in the code you recommend?

What content of prodjava.txt do you expect?

OK, almost got this! And, I probably didn't explain what I'm after very well. Based on the code you just provided, this is the output, e.g.:
somehost.mydomain.com
['java version "1.7.0_65"', 'OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)', 'OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)']
anotherhost.mydomain.com
['java version "1.7.0_65"', 'OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)', 'OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)']
anotherhost.mydomain.com
['java version "1.7.0_71"', 'Java(TM) SE Runtime Environment (build 1.7.0_71-b14)', 'Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)']
However, I only want records containing "Java(TM)" returned. How do I adjust the code to do that?

Sorry, I'm being messy here. If i try this, "select('search', '!OpenJDK|Java\(TM\)')|", I get output like this:
anotherhost.mydomain.com
['java version "1.7.0_71"', 'Java(TM) SE Runtime Environment (build 1.7.0_71-b14)', 'Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)']
