[antlr-interest] MismatchedTokenException in java parsing

[alexb577]

Hi,

I am a developer at www.argouml.org(opensource uml tool) and we use
the java.g grammar for reverse engineering to uml. Sometimes we get
these exceptions thrown and I hope that with the information I provide
you can help identify the problem and what we can do to fix it.

Below is the logged exception and filename it happened in, then a
snippet from the java file itself and then a brief statement to say
where the position of the error is.

we use a modified java.g, which you can find here if it helps:
http://argouml.tigris.org/source/browse/argouml/src_new/org/argouml/uml/reveng/java/java.g?rev=1.18&content-type=text/vnd.viewcvs-markup

Also, the java files do compile.

thanks in advance
Alex
