* remove dead code

* remove old comments

* [ci fw-only Java/greenlightning]

added comment

* [ci fw-only Java/greenlightning]

Added tests for remaining multi, update and fortunes

* [ci fw-only Java/greenlightning]

disable update test, seems to be missing some writes.

* [ci fw-only Java/greenlightning]

re-test of DBUpdate

* [ci fw-only Java/greenlightning]

disabled multi and update while tracking issue

* fixed muti paylod response JSON dups.

* [ci fw-only Java/greenlightning]

narrow building

* [ci skip] update readme

* [ci fw-only Java/greenlightning]

Update to version supporting 0.0.0.0 wildcard host

* [ci fw-only Java/greenlightning]

explicit memory min/max setting instead of default

update to new maven for build

* lower required low end to 8G

* [ci fw-only Java/greenlightning]

dropped min to 6G

* [ci fw-only Java/greenlightning]

memory reduction, was using as much as 20G, paging may have slowed test

reduce pipe memory allocations

combined behaviors to reduce memory

reduce db inflight collection to reduce memory

* Revert "[ci fw-only Java/greenlightning]"

This reverts commit 47c351db1ddeb64e65801f15e3c4398d5eca84ad.

* [ci fw-only Java/greenlightning]

Was using 16-20G which may cause paging and slow results

Reduced Pipe lenghts

Reduced concurrent connections

Combined behaviors to reduce Pipe counts for more memory.

Lowered limit to 16G to know it is enforced.

* removed minimum required memory in docker file

* [ci fw-only Java/greenlightning]  Ready for merge

* [ci fw-only Java/greenlightning]

Lowering memory usage to 7G from 14G

Clean up design to be easier to read

* [ci fw-only Java/greenlightning]

Investigating pef issue, returned threads to normal priority

Reduce the new and ongoing network kernel calls

Tread Executor using hardcoded count instead of asking docker

* [ci fw-only Java/greenlightning]

remove dead code

* [ci fw-only Java/greenlightning]

Test CentOS runtime in container

Add minimal logging to track runtime issues

* Revert "[ci fw-only Java/greenlightning]"

This reverts commit 7119eaa0df0f10ac5d5d6aca4bd15e04bc89de32.

* [ci fw-only Java/greenlightning]

added centOS in container as test

added minimal logging to debug deployment

* [ci fw-only Java/greenlightning]

1G less, narrow test scope
