[antlr-interest] charScanner panic.

[Vidar Håkestad]

There might be another problem that causes the panic() to be called:
If your AST/Token extensions have no default constructor, the panic()
will be called by the class loader, because it hav no way of default
constructing your class. So you have to:

public class MyToken extends antlr.Token {

   pulblic MyToken() {
      // Declare this constructor in order for
      // the class loader to instanciate your class
   }

      :
      :
}

The fact that there are code in the library that calls System.exit() is
quite annoying because it effectively kills any JVM it is part of,
including my JBoss application server.
