[antlr-interest] Remote Debug C Target parser

Hi Jim,
any update on this issue?
I have attempted to fix that by hand by taking the archive
http://www.antlr.org/download//C/libantlr3c-3.3-SNAPSHOT.tar.gz and
replacing the file ./src/antlr3debughandlers.c by the version present
in the git repository of Antlr on github (which has differences in the
sprintf format strings), and with that I could at least have a
beginning of debugging working with antlrworks. But after a few steps
antlrworks fails with this exception:
$ java -jar antlrworks-1.4.jar
java.lang.NullPointerException
java.lang.NullPointerException
at org.antlr.runtime.debug.RemoteDebugEventSocketListener.unEscapeNewlines(RemoteDebugEventSocketListener.java:515)
at org.antlr.runtime.debug.RemoteDebugEventSocketListener.deserializeToken(RemoteDebugEventSocketListener.java:453)
at org.antlr.runtime.debug.RemoteDebugEventSocketListener.dispatch(RemoteDebugEventSocketListener.java:301)
at org.antlr.runtime.debug.RemoteDebugEventSocketListener.eventHandler(RemoteDebugEventSocketListener.java:176)
at org.antlr.runtime.debug.RemoteDebugEventSocketListener.run(RemoteDebugEventSocketListener.java:472)
at java.lang.Thread.run(Thread.java:636)
This happens with the latest stable antlrworks jarfile available on
the website.
regards,
Guillaume
