>             Project: Pig
>          Issue Type: Bug
>          Components: impl
>            Reporter: Julien Le Dem
>            Priority: Minor
>
> This was raised while looking at PIG-1827
> There seems to be a bug in PreprocessorContext:
> http://svn.apache.org/viewvc/pig/trunk/src/org/apache/pig/tools/parameters/PreprocessorContext.java?view=markup
> {code}
> 235 	//String litVal = Matcher.quoteReplacement(val);
> 236 	replaced_line = replaced_line.replaceFirst("\\$"+key, val);
> {code}
> the replacement (2nd) parameter of replaceFirst is not a plain string, it can contain references to the matched pattern like "$0" so $ in val must be escaped.
> Does someone know why line 235 is commented out ?
