The following demo grammar causes ANTLR 3.4 to generate an invalid parser.
The conditional for the if statement is empty.
grammar Demo002;
number : '0'..'9';
java -classpath /usr/local/lib/antlr-3.4-complete.jar org.antlr.Tool
Demo002
In Demo002Parser.java
// Demo002.g:3:9: ( '0' .. '9' )
// Demo002.g:
{
if ( ) {
input.consume();
state.errorRecovery=false;
}
else {
MismatchedSetException mse = new
MismatchedSetException(null,input);
throw mse;
}
}
java -classpath /usr/local/lib/antlr-3.3-complete.jar org.antlr.Tool
Demo002.g
// Demo002.g:3:9: ( '0' .. '9' )
// Demo002.g:3:11: '0' .. '9'
{
matchRange('0','9');
}
