I also have Eclipse installed under 5.7 on a Latitude D530 with 2 gigs of ram but didn't really look into whether it worked or not, just went on installing more things.
Installing the swt package did the trick for me, I'm not sure why it got built but not installed. It was just sitting there in /usr/ports/packages/i386/all I installed Eclipse hoping to do Android development but I haven't tried that yet. It may be too old an Eclipse version. I also have Gradle running. And in another partition on this 1 TB drive is Debian Linux which has since run past the maximum cylinder the BIOS can address, just like the OpenBSD FAQ says may happen with it. Updated some key file, now it doesn't boot anymore, so it may get newfsed to OpenBSD space. Anyway Eclipse was the main reason I have Debian. If you're trying to do Android development, Android Studio I think is the only officially supported development environment, but it's just written in Java so it might be portable. As Stuart Henderson pointed out to me though Android is actually a Linux kernel running in Google's userland muck so running it under OpenBSD may be tricky. So your problem inspired me to fix my installation. Alan -- Credit is the root of all evil. - AB1JX
