Hi:

I’d expect two problems, the launcher and SWT.

1) The Eclipse launcher, i.e. the ‘css’ executable which opens the splash screen, arranges for the proper task bar icons and starts the JVM might not work on the BBB because it’s a binary for Intel Linux.

You could work around that by directly starting the JVM without the launcher.
This was actually necessary for a while on Mac OS X when Apple stopped supplying Java, and the Java from Sun/Oracle wasn’t recognized by the Eclipse launcher.
It looked like this:

java -showversion -XX:MaxPermSize=256m -Xms1024m -Xmx1024m -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -Xdock:icon=css.app/Contents/Resources/css.icns -Dosgi.requiredJavaVersion=1.7 -jar plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar

You could try to remove the Mac OS X - specific arguments and locate the current launcher jar version, so you end up with something like this:

java -Dosgi.requiredJavaVersion=1.8 -jar plugins/org.eclipse.equinox.launcher_*.jar

2) SWT
For anything you actually see on the screen, Eclipse uses SWT, which requires a specific binary for Windows, Linux, Mac OS X, 32 resp. 64 bit.
The one for Linux is unlikely to work on the BBB.

On the upside, CSS is mostly a client tool. You can still use the BBB as an IOC, then run the CSS UI client on regular Windows, Linux, Mac OS X  ;-)

Thanks,
Kay
