Crowd upgrade from 2.2.4 to 2.4.0 fails. Bootstrap Error: Not enabled: Crowd REST API

I am performing an upgrade on Crowd to the latest version according to the steps described on

But when I start the new installation, it fails and shows me the error page:

2012-02-10 17:20:14 fatal Required plugins failed to initialise. Please check the logs for errors and restart Crowd. Not enabled: Crowd REST API

Please help me, i want to get this up and running so my developers can continue with their jobs :)

This error usually occurs when your plugin imports a package from another bundle with a specific version constraint and either the bundle providing that package doesn't meet those version constraints, or there is no bundle available that provides the specified package.

Have you solved the problem? Because I have the same one.

Nope, haven't solved it yet. I will be downgrading to the previous version...

Okay, could you please answer if you solved the problem? Or if the downgrade works?

Thank you in advance.

I was able to get past this error by switching my JDK version from 1.7 to 1.6. (It was a slightly different problem, but was yeilding the same error message).

I got the same error with a fresh install using jdk 1.7. After switching to JDK 1.6 now it is working.

I am wondering if this has been report to Atlassians's support?
