It implies that there might be something not quite right about your 
grammar, but the timeouts can happen on busy or slow machines with 
complicated grammars. See the command line page in the wiki, where you 
will find the timeout option. Combining these you will get:

java -Xmx750M antlr.jar -Xconversiontimeout 10000 t.g
