One of my ANTLR grammars running in AntlrWorks throws:
“Cannot launch the debugger. Time-out waiting to connect to the remote parser.”
In the past this message usually goes away but this one is persistent. On searching the ANTLR lists (e.g. http://www.antlr.org/pipermail/antlr-interest/2009-June/034659.html) there are hints that the error message is nothing to do with what it seems but could be a grammar error.
Has anyone got tips as to how to “reboot” or find the bugs in this situation?
I’ve found that the Windows firewall rules can really interfere with the debugger, so make sure you haven’t set it to block the Java VM.
Also, try waiting a bit and then choosing the “Debug Remote” option, often the debugger just takes a little while and the main process times out, but the debugger does still come up.
