STS launch issue on Mac

Question

I started STS today and an error alert popped up asking me to look at the error log under /Users/salman/springsource/sts-2.6.0.RELEASE/configuration. That log file had the following stacktrace:

I tried the few solutions listed on this thread Eclipse freezing at startup - before loading workspace but nothing worked.

While I go and try a few different things and checkout a few more blog posts. I wouldn't mind getting a quick reply here.

EDIT: Here's my STS.ini. Does this make any sense kadaj?

-startup
../../../plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library

Answer 1

I was able to resolve it by removing the 'org.eclipse.osgi' folder under configuration and relaunching STS. Got a fresh build of this bundle in configuration folder. I think that is what was corrupted.

Answer 2

Follow the mentioned steps

1. Open Application
2. Locate STS
3. Right click and open package contents
4. navigate to eclipse folder
5. open sts.ini
6. Add -Xss128m -Xmn1024m
