#5 Main modules not loaded, something went wrong. We have only

[Anonymous]

I have created a run configuration in eclipse ( Helios version ) and have added the line
-Xmx512M -Dsun.io.useCanonCaches=false
in the VM arguments.
When I run the configuration for the Robocode main class I get this exception:

Main modules not loaded, something went wrong. We have only 1 modules
