[antlr-interest] Antlrworks Debug gives java.net.ConnectionException

[Chris Snyder]

Thanks for the response.

I had already tried that but it turns out not to be the problem. 

Apparently I have a grammar issue.
I clicked on the output window in the debugger and saw this:

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
	at org.antlr.runtime.DFA.unpackEncodedString(DFA.java:151)
	at MScriptLexer.<clinit>(MScriptLexer.java:14863)
	at __Test__.main(__Test__.java:9)

I tried increasing the heap with –Xmx1024m but am still getting this error.

I downloaded the antlr source and loaded everything up in Eclipse but that
class turns out to not in the source distribution I downloaded here
http://antlr.org/download.html. 

The DFA28_transitionS variable that it is being looped over and passed to
unpackEncodedString has 1344 Strings in it. Is there something I should look
for in my grammar to reduce this array size?

Thank you,
Chris

Try changing the port number in preferences, something else is possibly
using the same port.

Exception 

Hello, 

I’m trying to use the Antlrworks debugger locally but I keep getting the
error: 

java.net.ConnectException: Connection refused: connect 

and a dialog box that says: 

Cannot launch the debugger. 
Time-out waiting to connect to the remote parser. 

I tried turning off the Windows firewall but that didn’t help. 

Can someone provide the work around for this issue? 

Thanks, 
Chris
