[antlr-interest] Need advice resolving internal error from createLookaheadDFA

I'm working on a large grammar and I'm seeing the following error
message on several rules.

error(10):  internal error:
org.antlr.tool.Grammar.createLookaheadDFA(Grammar.java:864): could not
even do k=1 for decision 197

Using the -Xwatchconversion ANTLR option I'm able to determine which
rule the error message applies to.  However, I'm not sure how to
resolve the problem.

Can anybody tell me what this error means and offer advice on how to
resolve it.  Thanks.
