It is a repacking of IntelliJ IDea with the new Android plugin. IntelliJ 
is indeed mostly in Java

but does have some binary components (it's in ports).

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.

You wouldn't be running Android apps directly, you'd be running them
in the Android emulator, which was (and still may be) a fork of qemu, so 
it might

be possible to make the emulator run on OpenBSD.

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.

the only officially supported development environment, but it's just

So your problem inspired me to fix my installation.

Now the question is if this jar is proper bundle and if so if it's
mentioned somewhere in Eclipse OSGi configuration. Do you have
configuration/config.ini file? Is there a bundle list inside it or is
there kind of simple configuration use? i.e. have a look into
osgi.bundles= line.
If simple cofiguration is used, then take it's name and see
bundles.info inside configuration/ --
verify that org.eclipse.swt.gtk.openbsd is mentioned there in some
form.

I'm sorry but I can't verify myself as I don't have Eclipse running on
OBSD yet and on Linux I do have 4.5. release which may be quite
different from 3.x on OBSD...

I am pretty sure that you can fix it by doing "pkg_add swt". Commit
message for revision 1.78 of the Makefile for the port states:

"- fix run depend in sdk. it requires swt to run."

see 
http://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/devel/eclipse/sdk/Makefile

I don't think so. UnsatisfiedLinkError is usually a sign of not being
able to find the library, nothing more.
