could not launch eclipse

[dkalo]

Hi to all of you,

My home enviroment is a Windows 7 (32 bit). Suddenly I was unable to
launch eclipse. I deleted all previous
version of workspace and java and installed the latest java 5 jdk and
eclipse modelling bundle.

I receive the following message

Any hint ?

Cheers,

I haven't seen this particular error, but have you tried starting
eclipse with the -clean option to see if that helps?

Can you also post version of eclipse and eclim that you are using?
