and goes against what Joel Spolsky said about rewrite from scratch[1]

Joel at one time was the product manager(?) for Excel. Microsoft also got lambasted for trying to use an internally built cross platform solution to use the same codebase for Mac Office and Windows Office back in the mid 1990s. Microsoft even decided that it was better to use native tooling for both platforms.

There is a difference between "rewriting" and using native tools for each platform. Would you still want something using Java+Swing?

Why not? Is Java + Swing very heavy or something? Is NetBeans in Swing or something else? I've used NetBeans for C, C++, PHP and HTML5 on my old Core 2 Duo with 2 Gigs of RAM on Fedora during my uni years and it was fine by me. It lagged some but on that machine everything lagged and it was a full on IDE (not just a code editor) with some really nice features.

A Core 2 Duo should not lag running an IDE. I ran Visual 2008 on a Core 2 Duo with Sql Server running and it had 4GB of RAM.

Netbeans and almost every other Java IDE at the time was one of my major turn offs about using Java compared to using .Net + Visual Studio.

In fact, I still use the same Core 2 Duo 2.66Ghz with 4GB of RAM running Windows 10 as my Plex Server and it can transcode up to two streams simultaneously. I'll still use it interactively when I'm working from home and I'm mindlessly browsing the web while I am waiting on something.
