Exception in thread "SIGWINCH handler" in build #1030

Setup, Configuration and Use Installation

Since updating my installation with a snapshot > 980 I get this exception whenever I start the system. This identical exception get thrown about 20 times in a row.

Exception in thread "SIGWINCH handler" java.lang.UnsupportedOperationException

I have installed a completely fresh version without any configuration files except adding.cfg, which contains a few bindings.
Any ideas?
