StringIndexOutOfBoundsException error when trying to build a project Follow

Hi all,

   I am trying to install, configure and run (build) teamcity for a maven project I have.

   I have installed the TC version 7.1.3 (which is the latest I have available at work) in my win 7 machine running JDK 1.7.0_17. I have configured it to get my project from my SVN repository. But when I try to run it it fails. Looking into the Build Log tab in my localhost page it shows the following error...

Error occurred during initialization of VM
java.lang.ExceptionInInitializerError

Any ideas please?

Thanks
