[antlr-interest] Antlr Error Message

[Behdad Forghani]

Hello,

Has anybody seen this error before?
Exception in thread "main" java.lang.RuntimeException: more than one
node as root (TODO: make exception hierarchy)
	at
org.antlr.runtime.tree.BaseTreeAdaptor.becomeRoot(BaseTreeAdaptor.java:150)

The first rule of the grammar is:
moduleDefinitions :
	moduleDefinition+;

So, I do not think I have more than one root node.

In AntlrWorks I get a different error:
