RE: Eclipse Scala IDE 2.0.0 (RC4) for Scala 2.9 and 2.8 is out

I already found the problem ... and the solution.

The install/update of the plugin doesn't work with JDK7 (JDK7_02).
You need to switch to JDK6 (JDK6_29).
The install of the plugin is also much faster.
After installing you can switch back to JDK7.

> If you are currently using Scala IDE RC2 or older, please read carefully the following instructions to successfully upgrade. First, you will need to uninstall the 'JDT Weaving for Scala' feature. To do so, simply open Eclipse and click on the 'About Eclipse SDK' menu (you can access it under the 'Help' menu item if you are on Windows, or the 'Eclipse' menu item if you are on OSX). Then, click 'Installation Details' and look for the 'JDT Weaving for Scala' feature. Select it and click the 'Uninstall' button, located at the bottom right corner. Once 'JDT Weaving for Scala'  is uninstalled, go ahead and upgrade to RC4 as usual.

> The 2.8 compiler shipped with this version of the plugin is based on the development branch of 2.8.3, and is fully binary compatible with both 2.8.2 and 2.8.1. It contains the same improvements to the presentation compiler as the 2.9 version, and a number of bug fixes related to Java signatures. Also note that the 2.9.1 compiler shipped with this version of the plugin is fully binary compatile with both 2.9.0-1 and 2.9.0.
