Verified payara server, micro versions 5 and 6 with final release of eclipse plugin.
Everything looks fine other than the issue payara/ecosystem-support#64

Hello all,
I know this is really not my business, but please consider that this particular issue @Chandra0115 refered and which I opened is a rather impactful one.
The WildWebDeveloper team has issued a fix that ignores the missing URI and keeps the POM editor usable, but I think it has not yet been released (it is a snapshot fix).
As it stands right now, any developer that uses Eclipse and downloads the Payara Tools plugin will immedately lose support for POM autocompletion.

POM editor issue is now fixed in the PR #60
Updated binary: fish.payara.eclipse.update-2.1.0.zip
