#29 Runtime exception when opening new battle

[Flemming N. Larsen]

Reported by Luis Crespo:

When loading an existing battle, I get a runtime
exeception (sorry, I did not record the exception
dump and now I cannot replicate the bug until I run a
new version). As the battle does not get loaded, the
open battle command gets ignored. This will happen
until I close robocode and reopen it: after that, it
will support existing battles.
