I've received the following error when trying to open up a UML document after doing the latest update.

Code:

I have asked someone from the UML team to take a look.

Freightek,
Are there any more entries in the log?? Also what command line parameters are you using on your eclipse shortcut?
We suggest something like

Code:

-vmargs -Xms256M -Xmx128M

or higher.

Quote:

-Xms256M -Xmx128M

or maybe

Code:

-Xmx256M -Xms128M

?

The issue *might be* that the Eclipse plugin cache got stale after you updated to 4.0.2 as it sometimes does not cleanly rebuild after updates. To rectify the problem you'll need to restart Eclipse with the -clean flag one time: eclipse.exe -clean

That could also resolve the problem.
