That could indicate a change in your Java SDK. Are you sure you haven't installed a back rev? Java is _supposed_ to be backward compatible, so v1.6 can use v1.0 class files, but sometimes it doesn't work the other way, new class files can confuse an older JRE.
You might be able to fix things by recompiling everything, including the TOS tools, in your current environment. Otherwise I'm clueless too...
