Errors running builder 'JavaScript Validator'

[MiB]

I'm getting this since STS 2.8.0 om all web projects

"Errors occurred during the build.
Errors running builder 'JavaScript Validator' on project 'spisero.no'.
1"

Possibly because thus validation need java 6 and I'm on java 5.
I don't need JavaScript Validator, even though I turned it off unchecking "Client-side javascript validator". How can I turn this validation off for real?

There is another place to turn off validation. Go to Preferences -> JavaScript -> Validator -> Errors/Warnings. Maybe some of the settings here can help.

Yes, it did. Thank you.
I found also this blog article: Javascript Validator problem in Eclipse.

As I don't need this validation currently, I turned it off. I do still wonder what the error does mean though.
