So I have tried to reproduce this without success on my Windows machine.
- Windows 7 (unfortunately I don't have Windows XP)
- Java Hotspot (TM) 64-Bit Server VM (build 20.2-b06, mixed mode)
- Eclipse Java EE IDE for Web Developers, Version: Indigo Release, Build id: 20110615-0604
- Maven Integration for Eclipse (m2e) : Version 1.0.100.20110804-1717
- Forge Tools : Version 1.0.0.v20110915-1403-H14-M3
This combination starts Forge up without any issues. Can you verify what the specific version is of your Forge Tools plugins?
Cheers,
Koen
