[antlr-interest] antlr 3.1b1 problems with DebugEventSocketProxy?

[Doucette, Charles]

I am trying to debug a parser I generated with Antlr 3.1b1, and I'm seeing two at least problems:

This is an error:

java.lang.NullPointerException
at org.antlr.runtime.debug.DebugEventSocketProxy.transmit(DebugEventSocketProxy.java:116)
at org.antlr.runtime.debug.DebugEventSocketProxy.exitRule(DebugEventSocketProxy.java:130)
at com.vaultus.studio.vscript.parser.antlr.vscriptParser.vscript(vscriptParser.java:488)
at com.vaultus.studio.vscript.parser.plugin.VScriptSourceParser.parse(VScriptSourceParser.java:69)

Here's the code sequence that invokes this:

finally {

dbg.exitRule(getGrammarFileName(), "vscript");

decRuleLevel();

if ( getRuleLevel()==0 ) {dbg.terminate();}

}

I haven't yet looked at the Antlr source code to see exactly what is causing this problem.

This is a warning:

java.net.BindException: Address already in use: JVM_Bind
