Remove pre-apache NetBeans 8.2 plugin portal from settings.

[mbien]

• the plugins haven't been updated for a long time and are of limited use, some require pack200, others broke for other reasons -> lets remove the plugin portal from the settings
• commit contains a small language level cleanup, mostly try-with-resource blocks

there are currently 10 plugins on the old plugin portal:

there are currently some efforts to re-integrate CND back into NB, but this is without ETA.

closes #6810, NETBEANS-4096, NETBEANS-2719, NETBEANS-2599 (as won't-fix essentially)
related #6969, #6979, #6987

+1 I suggested this a few years back and was vetoed. I hope there's no argument that we have no choice now.

Is the Platform label to enable something in tests? Otherwise, I'd remove it - this is almost the opposite of what we usually mean by that categorization.

platform label activates some extra tests which don't fit to other labels, However, I checked and the tests for this module are disabled anyway:

netbeans/.github/workflows/main.yml

Lines 1310 to 1311 in 2c6e3a7

	# - name: nb/updatecenters
	# run: ant $OPTS -f nb/updatecenters test

(all tests fail locally)

removed the label

Ah, OK, thanks. Things like that might be better under a new label like IDE-branding or such. Anything under nb/ is quite specific to the IDE rather than the platform, so it seemed odd to label it that way. Can discuss that elsewhere as it's not relevant to this change.

Only eyeballed this, but makes sense (code wise and based on intention).

+1 for removal of Hibernate plugin as there is no much usage at this time. FYI, I am the original author of this plugin.

@codeNick7 awesome!

It is always a mixed feeling when something is removed, but in this case and to my understanding: the pre-apache plugin portal contained plugins which were either never donated to apache (license uncertainty) or couldn't find maintainers (the exception is CND which is work in progress). Since nothing can be rebuilt there and things start breaking, it had to go at some point.

Thanks for the comment - always great when original maintainers say hi :)

☹️This is bad. We need the portal for C++. Unpack200 can be found in the Java 8 JRE files.
Please put the portal back or update the heavily neglected C++ that comes by default.

[neilcsmith-net]

That portal is not coming back by default! You can easily add it back in yourself, as outlined at #7627 (comment)
