[antlr-interest] not closed multi-line comment cause infinite looping

Hi all,

I am using antlr 2.7.6 and one of the Java grammars to build a parser 
for my own language.

I decided to start with an empty grammar and add rules from that Java 
grammar while applying required adaptations for my language.

There is a ML_COMMENT lexer rule which causes an infinite loop when the 
its instance is left open (i.e. without a closing */). This happens even 
when I am testing it in the context of the original Java grammar.

/* For example:
not closed multi-line comment -- parsing never completes
package foo.bar.oji8.fds;
