When I try to open a UML repository, I get a swt error that kills the Eclipse workspace. I’ve read through your posts, but didn’t find any that directly address this. I’ve got vmargs set to xms128m and xmx256m. Any suggestions?

thanks,
Brian

This looks like an install issue, a lot of core exceptions here.

If you download Eclipse 3.1.2 SDK and unzip it to a new directory, then install MyEclipse 4.1.1 into a new directory and point it at your Eclipse install you just did and create a new workspace, can you create a new UMR file?

Also, the command line arguments are case sensative, they need to be: -Xms128m -Xmx256m

[BrianH]

I’ll give it a try and let you know what happens. I’ve got the args in the right case; I just didn’t write them that way in my post.

Thanks,
Brian

Thanks Brian, I would emphasize that the new directories for both installs and new workspace are critical (don’t just run the uninstaller or unzip ontop of existing ones). I want to rule out any possible craziness and you get up and running.
