Re: [linuxtools-dev] System-installed dependencies 
Alright, I went back to using "external" dependencies, and Eclipse is back to failing to start up.

Here's the exception I get in the log:

Do you see anything wrong with this?  I'm at my wits end trying to make Eclipse behave on Gentoo.

> Okay, so that *is* a requirement.  No, they're just plain old JARs.  So I will have to go back to my previous way of doing it: gutting the dependency JARs in the "plugins" directory and rewriting their manifests with "external" Bundle-ClassPath references to the system-installed JARs.  The reason I switched to using symlinks was that doing the "external" references was no longer allowing Eclipse to start up if there was no pre-established ~/.eclipse directory.  Hopefully I can figure out why that's happening.
